Creating a Slipcover for Your Crib Mattress

Creating a slip cover for your crib mattress is actually very easy. Even if you are not an experienced seamstress you can complete this job in an afternoon. You’ll even find that creating a slipcover for your crib mattress doesn’t always require a sewing machine. Don’t fear, with a little forethought and a small amount of creative ability you can create a personalized backdrop for your baby’s bed.

Step 1 – Consider the Material You Will Use

There are many materials you can use to make a slipcover for a crib mattress. However, organic cotton is thought to be the safest and gentlest for your baby. Organic cotton does not contain chemical dyes, perfumes, or any irritants that could harm your baby. However, you can find organic cotton that is dyed with vegetable dye, if you prefer something other than the bland color of organic cotton. If you choose not to use organic cotton make sure that the bedding you use is free of harsh chemicals or preservatives that can irritate your baby’s tender skin.

Step 2 – Choose between a Permanent or Temporary Cover

You have two options when creating a slipcover for your crib mattress. You can make a permanent slipcover that will never be removed, or you can create a temporary cover that can be removed for washing. temporary slipcovers are the best option. After all, babies often spit up and bottles may leak. If you use a permanent cover you will have to cut it off and use a new one every time the cover gets dirty.

Step 3 – Measuring the Right Dimensions

Before you begin you will need to measure your baby’s crib mattress. Remove the mattress from the crib and place it on the floor or a large table. Measure the length, height, and width of each end of the bed. Next, measure the sides, and finally the top and bottom. Write all of these measurements down with your pen and paper. You will notice that the matching sides, such as the top and bottom, usually have the same measurement within a half inch. It is usually best to use the biggest measurement for each part of the mattress. For example, use the biggest measurement out of the top and bottom.

Step 4 – Cutting Your Material

The next step you will complete is the cutting of the material. For most people this is the scariest part of the project. However, take your time and measure twice to make sure you have no problems. At this point you have three measurements. One measurement for the top and bottom, one for the sides of the mattress, and one for the ends of the mattress. Fold your material into two even pieces. Use the white chalk pencil to draw each of these measurements on the folded material. When you cut the three measurements out you will end up with two of each piece.

Step 5 – Sewing the Final Product

Now it is time to assemble all six pieces. Start by pining the two end pieces on the top of the slipcover. Using your sewing machine, sew these pieces together. You can sew a 1/4 inch seam for this project. After you attach the end you will want to attach the sides in the same manner. The final step is attaching the bottom and turning the piece right side out. Sew the bottom to side pieces of the slipcover. Next, sew the zipper to one end of the slip cover and the bottom. Now you can sew the final end piece and turn your slipcover inside out for use. If you prefer you can use the fusible tape to finish the slip cover instead of sewing the pieces.

How to Make a Mattress for Any Doll Bed

Do you remember a few months ago when I made the new bunk beds for our American Girl dolls? Well, our poor dolls have had nothing but a hard board to sleep on since then. I was just kind of dreading thedoll bedding pattern. Not that is it hard stuff to sew, it is just that sometimes I put off pulling out the sewing machine and making things like this. I think I make it worse than it really is in my mind. Ever been there, done that?

Well, I finally got over my mental block and made new mattresses for the new beds. Yay!

If you have been a follower of my blog for a long time, you may remember when I made bedding a few years ago for our first set of doll beds. This time Fairfield offered to sponsor this post and sent me a couple of products with which to make the doll mattress.

I had originally been planning to make the doll mattress in the exact same way that I made it a few years ago. However, when Fairfield sent me their project foam (affiliate link) as one of the possible items to use to make the mattress, I realized the 1″ thick foam would be perfect for the doll mattress. I also realized it would make the mattresses even easier to make. I always love when I can make a project more simple!

Now I realize that this isn’t directly a fun activity with the kids and myself, but I also know that when I make something like this for my girls they have a great time playing. To me, that helps make for a Real Summer of Fun. That is why I’m including this in my list of ideas for making this a summer of real fun. You can check out all the other Real Summer of Fun ideas in that post.

So let me show you how I made this doll mattress.


  • Doll bed(affiliate link)
  • 1″ Foamology Project Foam (affiliate link)
  • Fabric
  • Thread
  • Sewing machine
  • Pins
  • Fabric marker
  • Measuring tape
  • Scissors

Start by measuring your bed. This pattern can be adapted for any size doll bed.

Our doll beds happen to be the beds from IKEA that I painted and customized. The portion for the mattress measures 12″ x 19″.

You will want to add 1.5″ to your measurements. Cut your fabric at that measurement. My fabric cuts were 13.5 x 20.5″.

Cut two pieces of fabric at this size.

I tried making the mattress casing the same size as the original mattress that I made a few years ago, but because this foam is thicker than the batting that I used last time, I needed to increase the cut fabric size.

Mark off your Foamology 1″ Project Foam with the dimensions of your bed.

Mine was 12″ x 19″. I was making 2 mattresses. One for each of my daughter’s beds. I marked off two mattresses.

Cut your foam to size following the lines you marked.

Now you need to sew your mattress casing. Place the two right sides (or patterned sides) of your fabric together and pin. Sew with a 1/2″ seam leaving an opening at the top or bottom of the mattress.

Before you turn the mattress casing right side out, pull each corner to a point and pin. This will give you your box corners for the thickness of the mattress.

Since I was using 1″ foam, I marked a line across the pointed end at the point where it was 1″ across. Use a fabric marker for this.

Sew on that line making sure to backstitch both at the beginning and end. Clip the excess fabric.

Now here is where I made this a super simple project. Turn your fabric right side out and place the foam mattress inside. You will need to wiggle and work the foam into the corners.

Last time I made these mattresses, my mom was in town. She doesn’t mind doing the hand sewing. She wasn’t in town this time. I really dislike hand sewing. I decided that the mattresses were going to be closed on the machine. In order to do it that way, you will need to pin the opening closed. Then add a second row of pins that will allow room for the presser foot, kind of like when I turned the one IKEA pillow into two.

To get a really narrow seam, if your machine has the ability to move the needle position, move the needle position to the right. Sew the opening closed remembering to backstitch both at the beginning and end.

Easy peasy! It may not look as perfect as the hand sewn closure, but it entailed no swear words and a happier mom, so it worked fantastically for me!

The dolls love their mattresses as well. They don’t mind that I went for the easy closure. I also didn’t add any buttons to the mattress this time. You could add a few buttons to help hold the mattress in place. I dislike sewing buttons as well and the foam is in the casing nice and snug, so I think it will have a hard time sliding around (which would be the point of the buttons).

These doll bed mattresses are just adorable. Both of my girls really thought about the paint for the bed as well as matching the bedding to the paint. So far they look great! Next week, I should be able to show you the reversible sheets we are going to add to the doll bedding.

In the meantime, you can whip up a doll bed mattress easy peasy. You can sew with your kids or you can sew it for them. Either way, it gives something fun for your Real Summer of Fun.

How to Build a Homemade Baby Cradle

Building a homemadebaby cradlewill not only save you money, but it will serve as a functional and charming heirloom that will soothe a newborn and can be passed down through generations. This quick and easy project can be inexpensively and sturdily built using a combination of oak hardwood and plywood. With a few screws, woodworker’s glue and varnish, you can build and finish a homemade cradle in two weekends.

Tools and Materials

All measurements are thickness by width by length in inches for oak hardwood unless otherwise specified as plywood.

  • 2 end panels of ¾x22x15 pieces of plywood
  • 2 bottom rocker boards 1×4½x29
  • 2 top rail boards 1x5x28
  • 4 upright pieces 1×1½x29¼
  • 2 center rail boards 1×3-1/4×20
  • 2 cleat pieces 3/4×3/4×16½
  • 2 lower side rails 3/4×3-1/4×36½
  • 2 upper top rails 3/4x2x36-1/2
  • 32 inner slats ¼x1x7-1/4
  • 68 slat spacers ¼x5/16×1¼
  • 2 lower rail cleats ¾x¾x36½
  • 1 cradle bottom ½x18¼x36-7/16 piece of plywood
  • Assorted wood screws
  • Router
  • Straight groove router bit
  • Sandpaper if grits from 100 to 220
  • Varnish

Step 1 – Measure and Cut Wood

Begin by cutting all the pieces in the bill of materials out of either Red or White oak to the sizes suggested. Some of these pieces will be modified such as the rocker boards, top rail boards and plywood end panels.

Step 2 – Shape Pieces

Attach the two bottom rocker boards together with double-sided masking tape. With a pencil and a bowed piece of 1/8-inch piece of wood, design and mark out an arch along the bottom of the bottom rocker boards. Carefully band saw along the curved line to cut out the bottom rocker boards. Attach the two top rail boards in the same manner, mark out an arch, and carefully band saw a curve along the top of the top rail boards.

Step 3 – Build Two End Frames

Using the two upright pieces (D),one center rail (E), the curved top and bottom rails (B and C) form the 2 end frames. Glue and clamp these together securely. When glue has dried thoroughly, clamp each piece to a work table, and using a router with a straight grooving bit route out a ¾ inch groove in the upper inside frame. Apply a thin bead of glue and clamp a fitted plywood end panel (A) into this groove.

Step 4 – Assemble Side Panels

Router grooves in lower and upper side rails (G and H), apply spacers (J) and slats (I) to form railings for the home made baby cradle.

Step 5 – Affix Cleats and Cradle Bottom

Screw and glue cleats (K) to bottom of side panels and end frames. Fit plywood bottom (L) into cleats. It is not necessary to glue or screw bottom piece into cleats as it may be necessary to remove and replace it in the future.

Step 6 – Apply Finish

Finish sanding the entire baby cradle with sandpaper, working from 100 to 220 grit. Wipe clean to remove all dust. Begin applying a 25 to 75 percent solution of varnish and minerial spirits, and finish with a final coat of 100 percent varnish.

How do you make a cradle mattress

  • Crib
  • Thick foam, like what you take camping
  • Pillowcase
  • Matching thread, for mattress cover and sheet if needed
  • 1/2 yard fabric for sheet
  • 1 pkg 1/4" elastic
  • Sewing supplies (including scissors, pins, sewing machine, measuring tape, and iron)
  • Helpful to have: straight edge, and marker.

Let’s begin.

Step One.Measure your crib, and cut the foam to the correct size.

Take out the pillow case, and slip the foam inside it.

You’ll want to leave about an inch on each open side. Remove the pins and the foam, and turn the pillowcase wrong side out. Stitch the seam closed along the long side of the mattress. I used a 1/2" seam. Turn the pillowcase right side out again, and re-insert the foam.

To close up the final seam, fold the fabric as shown. like you’re wrapping a present. I tucked in the short edges, then pressed the top down.

For the final fold, I ironed down the flap about 1", so that no cut edges would show.

Finally, hand sew the mattress closed.

Now at this point, you may be wondering why in the world I went to the trouble of covering the mattress. I covered the mattress so I could make a small removable sheet. Yes, I wanted my girls to practice changing sheets.

There are sacred moments in the everyday service I provide my family. (I’m still trying to convince my oldest boy that changing sheets is not only hygienically necessary, but also feels so good to get into). Sometimes it is difficult to see family work as just that. working together as a family rather than drudgery. But to my mind, the physical and spiritual parts of our lives are not separate, they are blended. The little things we do to care for our families have eternal consequences. Each act of service knits our hearts together. You can’t help but love those you serve.

So on to making the crib sheet.

Step Three.Determine the size you need.
To make your sheet fit the mattress, measure the width and length of your mattress. Now measure the depth of your mattress, and double it plus 1/2", adding this to your original size.[EDIT: You need need the width of the mattress plus half an inch for EACH side, so in this case that equals to 5.5" additional width.]
For example, my mattress is 12" wide by 24" long, and 1" wide. So, I cut out a rectangle for my sheet that was 17 1/2" by 29 1/2".

Step Four.Trim your corners, and make a box.
To make the seams to fit the corners of the mattress, cut out a square from each corner. The size of the square will be determined by the depth of your mattress. You’ll take out double the depth, or in this case, 2".

Sew each corner together.

Hint: If I was making this for a full-size crib sheet, I would have finished the edges with a zigzag stitch.

Fold the fabric down again, this time 1/2". Pin in place, and then sew 1/8" from the edge.

Be sure to leave about a 1" gap between the beginning of your seam and the end to be able to slip your elastic through.

Cut your elastic to length. I found that half of the perimeter was plenty. In this case, one long side was 25" and one short side was 13", which meant 38" of elastic. I used less in this example. and it pulled a little too much. Half the perimeter should be plenty.

Slip a safety pin onto one end of the elastic.

Slip the elastic into the casing, and sew the casing closed, following the same topstitching line you used before.

Congratulations! Now slip the sheet on and make sure it fits snugly.

How to Sew Mini Crib Sheets (Easy With Pictures)

Getting Started

If you own a mini crib, most likely the Alma Mini Crib, you have found out that there is only one crib sheet available on the market. Itisorganic, but it it’s only plain white and kind of pricey. Here are easy, step-by-step directions on how to make your own.

You will need 1-½ yards of fabric for each sheet you want to make (you should be able to make one with 1-¼ yards, but if you shop somewhere where they cut fabric pretty crookedly, you might be cutting it too close, so better to be safe). You will also need 54” of ¼” elastic for each sheet you make, a medium sized safety pin, and of course sewing thread.

Next, you’ll need to wash, dry and iron your fabric or fabrics – if they are very different colors or you are unsure of how colorfast they are it’s a good idea to launder them separately.

Cutting Your Fabric

Trim your fabric to make sure it’s square/straight. This step was especially important for the sheets I made, because all three patterns were on a grid and any crookedness would have been evident once the sheets were done. Now you’re ready for the real work.

Cut your fabric down to a 48 ½” X 30 ¾” rectangle. (SEE NOTE AT BOTTOM FOR DIFFERENT SIZED BABY MATTRESSES.)

Then cut out what I call the corner squares; these are 4 ¼” X 4 ¼”.

Here’s what the piece of fabric looks like once it’s been cut:

Pinning and Sewing Your Corners

Now you’re almost ready to start sewing. First pin the right sides of each of the corner squares together. You could do these one at the time – pin one corner, go sew it then pin the next corner and so on – but I prefer to pin them all and then go sew them all at once.

Sew each corner using about a ¼ “seam. Although you want your fabrics cut straight, absolutely precise seams are not necessary (this is not a quilt!) and most of the sewing ends up under the mattress where no one will see it.

Once you have your four corners sewn, press your seams open.

Making the Elastic Pocket

Next you’re going to create the elastic pocket. You first go around the sheet and press in a ¼” all the way around. Then you go around again and press in about another ½”. You just need to make sure that your elastic will fit inside the pocket you’re creating – you can see how I tested this in the photos below. You’ll also need to make sure to sew your pocket seam to the outside edge of the fold to make sure to allow enough space for you elastic and safety pin to pass through. Place pins every 10” or so as you work your way around the second time to hold the fold in place when you sew.

Now you’re going to sew your elastic pocket. In order to avoid accidentally sewing all the way around, I like to place a pair of pins at a 90 degree angle about 10” apart where I want to start and stop my sewing. These act as my red flags. You want at least 10” left un-sewn because it’s a lot easier to join the ends of the elastic when you have some wiggle room. For the same reason, I also find it easier to start and stop on one of the long sides of the sheet.

Feeding the Elastic

Once you have your elastic pocket sewn and leaving about a 10”+ gap, you can now add the elastic. Adding the elastic is probably the hardest part of this project, but it’s really pretty easy once you get the hang of it. The measurement of the elastic is somewhat debatable. I’d say that using a 52” length would make a snug fitting sheet that is still easy to get on and off. Of course, if you like it snugger or looser, adjust your elastic length accordingly. Take your safety pin and attach it to the center of one end of your elastic (seems silly to emphasize center, but I’ve learned the hard way that if you attach it closer to the edge of the elastic sometimes the elastic frays and falls apart midway through your "feeding" process and you have to start all over).

So, you want to feed your safety-pin into the elastic pocket. Slide it as far forward as you can, then with your other hand hold the safety pin in place through the fabric and pull the fabric you’ve just fed the safety pin into back over the elastic.

Continue doing this until you’ve made it all the way around. Once you get all the way around, make sure to hold the safety pin firmly and spread the fabric around the elastic evenly (because it will most likely be bunched up by the end of your safety pin). If you need to put the sheet down for a minute at this point, make sure to safety pin both ends of the elastic together, so that the end of the elastic doesn’t accidentally slip back out of the pocket.

You can also take the sheet as is and place it on your mattress to see how taut it is and if you want to shorten or lengthen your elastic before doing the final sewing.

Final Steps

Now take the two ends of your elastic and lay them over each other and pin them in place. Place this under your presser foot and sew it together (obviously removing the pins as you go). You might want to go over this seam a couple times to reinforce it.

The last step is to sew those last 10”+ of your elastic pocket. There you go! You have a beautiful, custom mini crib sheet.

You’ll notice that when not on the mattress they sort of look like oversized fabric shower caps.

Notes for Different Sized Mattresses

NOTE: Since I’ve received many comments asking what size fabric to start with for different sized baby mattresses, I thought I’d add this helpful tip.

If you’re mattress is 3"-4" thick, you just add 12" to the length and width of your mattress dimensions. For example:

Your mattress is 10" wide x 3" thick x 20" long.

That means your fabric should be cut to 22" wide x 32".

And then you just follow the rest of the directions from there on.

Questions & Answers

What size fabric should I use when sewing crib sheets if my mattress is 20" x 30" x 1"?

You should start with a 24"x34" piece of fabric and cut 3" squares out of the corners. Follow the rest of the directions as is.

Crib size is 26 x 37. The depth is 3/4”. What size should I cut the fabric when sewing a crib sheet?

What size of material would I need for a mattress that is 36 1/2 x 16 1/2 x2 inches?

Jennifer Anderson

Hello, I’m going to make a sheet for a changing table. The pad is 30 3/4× 18× 3/4. What will the demintions be and how do you figure it out please.


2 years ago from Sacramento, CA

For your sized mattress I would use a 31" x 21" piece of fabric, cut out 2.75" corner squares, and then follow the directions as is.

Good luck with your project!


Also how big would the square cut out need to be?


Hi I am making mini crib sheets for a baby box the mattress is 16.25 x 26.25 x 1.5, please advise how big I need to cut my fabric and how long to cut my elastic. Many thanks.


2 years ago from Sacramento, CA

Thank you for your question. Based on the dimensions you provided, you would need to start with a 42"x30.5" piece of fabric, and then follow the directions as is from there.

Good luck with your project!


Hi! I am making a fitted sheet for a mattress but its only 1.5 in deep. Can you tell me how big to cut? Its 37.5 long, 26 wide and 1.5 deep.


This was the easiest instructions to follow. Clear concise and I was able to make two flannel crib sheets perfect fir the quilt I’m making plus two receiving blankets. Thank you you the great tutorial!

Jenn Muhlena

Found this site by chance and what a great help! Thank you. The measurement tips worked out perfectly! Thank you again!


This is very helpful. I’m making sheets for an old family cradle. I had to custom order a mattress 12 x 33 x 2 inches. Do you think you have a formula for something that small?


I am trying to make a cushion cover using your pattern but I am having trouble The cushion size is 44 x18 x 1. Please tell me how long fabric should be and how much to cut from the corners. I’m also making 2 sheets for my grandson. Your instructions are wonderful. Thank you


3 years ago from Sacramento, CA

My apologies for not responding sooner – I somehow missed your comment when you originally posted it! Hopefully you were able to figure out what size you needed and had success in making your crib sheets.

I looked at your mattress dimensions and came up with a 37" x 50" rectangle with 6 1/2" squares cut out at the corners. I’m sure the dimensions you came up with work too, as the mattresses are pretty forgiving.

Fee free to post your crib quilt link too.


3 years ago from Sacramento, CA

Based on your mattress measurements, you should use a 40"x 21.5" piece of fabric and cut out 3.5" squares at the corners and then follow the rest of the directions as is.

Good luck with your project!


my mattress pad is for a square bassinette. My measurements are 14 1/2′ wide and 33 " long and a 2" pad. I have the foam cut. Now I need to know how to cut my corners. Its for a friend and she wants a box corner on each corner of the mattress. I need help. Thanks


Your tutorial is amazing and I look forward to creating 3 fitted sheets for my little one. I hate to bother you with this question since you’ve given instructions for the measurements several times however my math isn’t adding up to what you’ve told some others. I’m very much a newbie at sewing so I want to make sure I have all measurements correct before cutting and wasting fabric.

I’ll be creating fitted sheets for the Davinci Crescent Mini Crib 50 Coil Mattress.

The measurements are as follows:

37"L x 24"W x 5" D.

I calculated that I would need 54" X 41" fabric with 6 1/2" corner cutout.

However when you answered Olivia’s Post from

2 years ago in which or Length and width’s are the same you instructed her to use 56" X 43" fabric. Can you tell me advise me on wether I should go with my calculations or those that you gave to Olivia? Please and thank you!

Also, A while back there were some that were interested in a mini crib quilt pattern. I found a lovely easy to follow free tutorial that I’m willing to share with the blessing of Mrs. Genevieve. Thanks!

It sounds like the elastic is probably too loose. That measurement is definitely not exact as it depend on the elasticity of the elastic – some stretch more than others. You can open it up and shorten it to the point that it is snug on the mattress, which is how I did it. I test it with a safety pin holding it at length before sewing it together and sewing the seam shut.

I hope this helps.

Hannah Caudle

My apologies, meant to mention that this sheet was for a friend lol

Hannah Caudle

I sewed up an Alma Mini Crib Sheet using you exact dimensions down to the smallest measurement and made sure her mattress was the correct dimensions. Now she’s upset though because she said it is too loose and is a hazard to her child. Why did this happen when I precisely followed your directions? Is 54" of elastic too much?? Does she need to just simply open the seam and shorten the elastic?

I am so happy to hear that your project turned out well. 🙂


Thank you for the great instructions and for helping resize the measurements! This was one of my first real sewing projects and the mini crib sheet looks adorable. Saved so much money! Thank you Thank you!



4 years ago from Sacramento, CA

Based on your mattress dimensions (1" x 18 1/2" x 35 1/2"), I would use a 23" x 40" piece of fabric and cut out 2 1/4" squares on each corner and follow the rest of the directions as is.

Good luck with your project!


I have a mini crib mattress & the sizes are 1in thick 181/2 inches wide and 351/2inches long . Can you please help me with the measurements and the square cut out ?? Please .


Thank you so much! I have looked everywhere and cannot find reasonably priced sheets to fit this mattress! I am so excited!


4 years ago from Sacramento, CA

You would need a 37"x51" piece of fabric and to cut out 6.5" squares at the corners. You would then just follow the directions as usual.

Good luck with your project!


Hi Genevieve, I need to make a portable crib mattress sheet for a mattress that is 5" thick. The mattress is 38.0 x 24.0 x 5.0 Could you help me figure out what size I cut out and how large the square i would cut out? Thanks!


Genevieve. this was a fabulous tutorial!!



4 years ago from Sacramento, CA

I don’t mind the question at all, and it seems to come up a lot. I actually got the -4" from another expert sewing blog. However, I personally do what I show in the article. I feed it through the channel, safety pin the ends together where I think it works best, even try it on the mattress, remove it and then carefully sew the ends together. It is difficult to give an exact measurement, because it will depend on how much stretch or give there is in the fabric you are using, etc. If you have a really stretchy fabric, the elastic may need to be a lot shorter.

I hope that helps! 🙂


Genevieve – I am going to drive you crazy, sorry. The crib mattress is 36x23x3. What would you say the elastic would be. Somewhere I saw circumference minus 4" but that really doesn’t work. I cut it in half and that seems to work.

My daughter loves Minky fabric too, so I am not surprised by this request. The challenge with Minky fabric is that you cannot iron it/press it, because it would melt. The step where this is most helpful is when you make the channel for the elastic. If you think you could fold the Minky twice over and sort of finger press it into place, then I’m sure it would work out great. No one will be looking under the mattress, so if your channel is a little wavy no one will know. I’d also look at getting a thinner needle that works well with thicker fabrics.

I hope that helps and good luck with your project!


Now I have a question about fabric. I see 100% cotton is the best fabric. I have seen it in Cotton, Jersey and Flannel, but my daughter wants minky fabric. Now I am worried about that, how do you feel about that.


Genevieve great information. I am getting ready to start one for my daughter. This is the calculations I get after reading everything. Is this correct?

Width = Width + Depth (times 2) + 7"

Length = Length + Depth (times 2) + 7"

Cutouts = Depth + 1 1/2"

Elastic = Circumference of Mattress minus 2" to 4"

Fabric = 100% cotton

The rule of thumb is to cut your elastic about 2" shorter than your circumference. In your case that is 198" minus 2", which would be 196". However, I find it best to feed the elastic and connect the ends with a safety pin to test it out before finalizing the length. I hope this helps.

Good luck with your project!

I am not clear what your first question means, could you clarify further. The Alma mattress is not waterproof, and you should definitely remove the plastic – it’s a suffocation hazard. I would use high quality quilting cotton, which you can find at any Joann’s store.

Good luck with your project!

You could definitely serge the raw fabric edges before sewing them together. However, most people don’t have sergers or know how to to do that and the sheets held up just fine through the amount of time the baby and toddler used them. I hope that helps.

Good luck with your project!


I noticed in the section where you cut the 4 corners, you then sew them together, and then press the seams outward. however, they are raw fabric edges. your pictures don’t look like you serged or hemmed them. Didn’t they end up fraying badly when you washed the sheets??

I’ve done a little research on calculating elastic lengths, and my best recommendation, is to take the overall circumference of the mattress and subtract 4". In your case, that should make the elastic 120".

I hope that helps. Good luck with your project!


Hi! I’m using this tutorial to make crib sheets for my little sister’s mini crib mattress (LA baby compact crib 3" mattress). The dimensions are 38x24x3 so I was planning on on cutting 50 x 36 rectangles with 4.5 corners. I’m hung up on the elastic though. Has anyone made a sheet for this size mattress and can recall the length of elastic used? I don’t have the mattress in my possession (she’s on the other side of the country) and she doesn’t sew at all, so it will need to be completely finished when it gets to her!


What would happen if I cut D+2 1/2 for the corners, instead of D + 1 1/2. I think I just cut it wrong and am trying to figure out if I can still sew it or if I should start over.

If your mattress is 38x3x24, you will need a piece of fabric that is 50×36, and then follow the rest of the directions, including cutting out the 4 1/4 x4 1/4 squares from each of the corners.

Good luck with your project!


I have a dream on me mini crib mattress that measures 38x24x3. How much fabric and elastic should I get? Thank u

I am not sure what you mean in question 1. Are thinking of making more of a pillow case? Regarding question 2: The Alma mattress is not waterproof and they sell mattress protectors for it, that you can put under the sheet. And 3: I would use 100% cotton like the kind used for quilting, which you can find at any fabric store.

Good luck with your project!

hi, thanks for the tutorial. three questions:

1. I was thinking of just tugging the fabric over the mattress.. so would I need more than 1.5 yards of fabric? I have the alma too.

2. is the alma mattress waterproof? it came with plastic wrapped and I was t sure if I should take that plastic out?

3. what type if fabric should I get??


5 years ago from Sacramento, CA

If I understand correctly, your mattress dimensions are 56 x 43, so the total circumference is about 198. Based on how my sheets have turned out, I’d estimate your elastic to be around 100. However, because the depth of the mattress affects this, and some people like snugger or looser fitting sheets (pros and cons to each: one is hard to get on but stays on like a charm and vice versa), I would keep the elastic about 20 longer at 120. Feed that through your elastic pocket and then pin it with a safety pin to see where you’d like the length to be, and then follow the rest of the directions.

I hope that helps.

Good luck with your project!


If I make the larger sheet, 56 x 43, how long do I cut the elastic?

Unfortunately I do not have a pattern for a crib skirt or crib quilt. I would try searching on Etsy. Also, a lot of quilt and fabric designers offer free quilt patterns on their websites/blogs.

Good luck with your project.

Hello I am looking for direction to make a crib quilt and skirt for a mini crib..


6 years ago from Sacramento, CA

Thanks Kathy! I’m glad you found these directions helpful. Good luck with your project!


Great, easy to read and follow instructions Genevieve. And the comments were so helpful as well. I’ve been searching for easy to follow instructions to make cute sheets for our church nursery which has new mini cribs. Thanks everyone!

I would need to know how deep your mattress is too. I am also not certain what you mean by 1/2" hems. My directions include allowances for the elastic pocket, and the sheet wraps around the bottom of the mattress securely, but there is no hem per se. Once you give me your mattress depth, I can help you with the size of your fabric.


My mattress is 14×33. What size should my cutouts be? Also, do you allow for 1/2" hems in your measurements? Your instructions seem clear and precise–thanks for the pictures–can’t wait to try it.

You should use a 36"x42" piece of fabric and cut out 3" squares at the corners and then follow the rest of the directions as usual.


Our minicrib mattress is 28x34x1.5 what size should my cut out be? Thank you so much!


If this helps anyone: Im making sheets for the Dream on Me 3" mini mattress and Im cutting a 51" x 37" rectangle with 4.5" corners. The mattress is 38"x 24" x 3".


7 years ago from Sacramento, CA

Yes the piece of fabric you would need is 56×43, and I would cut out 7 1/2" corners. I should have mentioned in my last answer that to calculate the corners, you take the depth of your mattress – in this case it is 6" – and add another 1 1/2" to accommodate the elastic pocket and ensure it will tuck under the mattress. Good luck with your project!


I have a mini crib mattress that is about 37x24x6. Would it be correct to then work with a 56×43 fabric square? How do I figure out how much to cut out for the corners?


7 years ago from Sacramento, CA

I believe you should use a 44"x 26" piece and cut out four 3-1/4" corners and then follow my directions for assembly. Basically I take the length dimension and add the depth of the mattress (not forgeting to double the depth so that it covers both sides) and then add 7" to the total to allow for the elastic pocket and for it to wrap under the mattress, and then I do the same for the width dimension.

I hope that helps.

Good luck with your project.


You instructions for the mini crib sheet is fabulous. Very easy to follow instructions with your photos.


I have a mattress that is 15" x 2" x 33" which is for a bassinet. How do I figure out how much fabric I need and how much would I need to cut out from the corners. Your help would be greatly appreciated.


7 years ago from Sacramento, CA

This mattress is 18"x35.5"x3". It was for an Alma mini crib. Hope that helps.


What size is this mattress?


If I have a 5 inch thick mini crib mattress would my corner squares need to be cut out bigger than the 4 1/4? Please help!


Wow, amazing. I have been looking for mini crib bedding and it is so expensive and there aren’t a lot of styles to choose from. So, thanks to you, I am going to try to make my own. At, least I can design it exactly how I want it.


what size is the mattress? I am trying to make fitted sheets for a matress that is 37.5 x 23 x 2


Great tutorial! So easy. Thanks.
