How to Join Knitted Pieces with the Mattress Stitch

Mattress stitch makes a practically invisible and nicely flexible seam for joining pieces side to side. You can’t use mattress stitch successfully, however, on pieces that don’t have the same number of rows or a difference of only 1 or 2 rows.

1 Lay out your pieces next to each other, right sides facing up, bottom edges toward you.

You seam from the bottom edge up. If you’ve left a tail of yarn at the cast-on edge, you can use it to get started.

2 Locate the running thread between the first and second stitches on the bottom row of one piece.

Gently pull apart the first 2 edge stitches to see the series of little horizontal — running — threads connecting them.

3 Thread the tail of yarn or a fresh piece on a tapestry needle.

Make sure your tapestry needle is blunt to avoid piercing the yarn.

4 Join the bottom edges of the pieces, using a figure eight.

Work through the two threads on the cast-on row.

5 Bring your needle under the thread; then pick up the running thread between the first and second stitches on the opposing piece.

This step begins your mattress stitch pattern.

6 Work back and forth from running thread to running thread to running thread, keeping the tension easy but firm.

Check the tension by pulling laterally on the seam from time to time. The amount of give should be the same as between 2 stitches.

Crochet Invisible Seams with the Mattress Stitch

Crocheting For Dummies, + Video, 3rd Edition

Themattress stitch,also known as theinvisible seamorinvisible weaving,is a very flexible seam that works best for sewing garment pieces together because it makes for a flat, invisible seam. You always work this stitch with the right sides facing up so you can make sure the seam is invisible on its best side.

The key to this stitch is to make small stitches, weaving your needle back and forth between the two pieces while working up the inside of the edges to be joined.

Here’s how to use the mattress stitch to sew the row ends of two pieces worked in double crochet:

  1. Place the pieces to be joined on a flat table with the right sides facing you.
    The pieces should be side by side. Make sure the stitches themselves are aligned and that any stripes or patterns are aligned, too. (If you’re having trouble keeping everything aligned, you can always use safety pins or sewing pins to keep the 2 pieces together.)
  2. With an 18-inch length of yarn (or the long tail end) threaded onto a yarn needle, insert the needle up through the bottom-most stitch of 1 piece and out the middle of the post, or turning chain, of the same stitch, as shown in part a.

If you’re not using a tail end, leave a 6-inch tail with your first stitch so you can weave it in later.

  • Insert your needle up through the corresponding stitch of the second piece and out the middle of the post, or turning chain, of the stitch, like in part b of the preceding image.
    If you aren’t using a secured tail end, weave the needle through the same stitches referenced in Steps 2 and 3 to secure the yarn.
  • Insert your needle in the same spot where the last stitch came out on the opposite piece and bring it up and out the top of the double crochet stitch (dc), as in part a of this image.
  • The following figure presents you with two finished pieces joined with the mattress stitch. Part a shows the opened mattress stitch; Part b shows the complete, closed mattress stitch.

    You can work the mattress stitch to join pieces of any stitch height. Just make sure you weave the yarn back and forth using evenly spaced stitches. For single crochet stitches, simply insert the needle through the bottom-most stitch and out the top of the same stitch; then do the same for the corresponding stitch on the second piece. For the next row, move up to the next stitch. For the triple crochet, weave the needle back and forth three times for each post before moving on to the next row.

    If you’re using the mattress stitch along the top loops of a row, simply follow the preceding steps for sewing the row ends; just be sure to keep your stitches short.

    If you have two pieces of crochet to sew together, you may want to use the Mattress Stitch. A favorite when it comes to joining crocheted granny squares or crocheted clothing.

    How to Sew the Mattress Stitch

    When joining crochet pieces you can either slip stitch them together, single crochet them together, whip stitch them together or mattress stitch them together. I find that the mattress stitch creates the most seamless and invisible seam, and it does so without the ridge inherent in most other methods of joining crochet pieces.

    See a video tutorial using this stitch below.

    To join two pieces of crochet together:

    1. Lay out the two edges that will be sewn, lining up the corresponding stitches on each side.

    2. Thread your yarn needle with the main color of yarn.

    3. Work from the inside/bottom out, sew through each side as if you were lacing a pair of tennis shoes.

    4. Continue sewing back and forth from the inside/bottom out between both pieces to end.

    5. When finished sewing two pieces together, weave in the yarn end as usual.

    That’s it! I love how this method of joining eliminates the ridge you get when using most other methods of joining two pieces in crochet such as the single, slip or whip stitch.

    I use the Mattress Stitch to join the two shoulders together in the Painted Canyon Cardigan as well as the child sizes of the Unicorn Hoodie! See a video of the Mattress Stitch in action:

    How to mattress stitch your knits

    Published on 28 March 2019 2 min read

    So you’ve decided to knit a snuggly jumper, and you’ve done an amazing job so far. Except your jumper is still in several pieces, and now you need to sew it up! Don’t worry – we’ve all been there, and once you’ve mastered how to mattress stitch, you’ll be good to go.

    Follow our super easy step-by-step guide to mattress stitch knitting and you can finish up projects with invisible stitch lines and a perfect professional finish!

    What is a mattress stitch?

    A mattress stitch is a vertical invisible seam that joins two knit pieces together side by side. The seam itself is flexible, neat and firm, making it perfect for finishing up several projects – from jumpers and cushions, to that vibrant patchwork blanket you’ve always wanted to finish.

    When should I use a mattress stitch?

    A mattress stitch only works when the two pieces have an identical number of stitched rows. It’s perfect for patterns that use the stockinette stitch or ribbing. You’ll want to use it whenever you’re looking for a flat join. Because the stitch is externally invisible, it can even come in handy to make any necessary size adjustments.

    How to mattress stitch step-by-step

    Lay down the knitting.Place the two pieces to be joined side-by-side, with the right side facing you.

    Cut your yarn.As we want this stitch to be invisible, use the same yarn you’ve knitted with (though we’ve used contrasting yarn to show you how to do it). Measure out a piece about three times the length of the seam you want to join, and thread it through a blunt darning needle.

    Thread your yarn through the first stitch.Beginning with the left side of the knitting, take your darning needle and insert it into the bottom right hand corner of the first stitch.

    Insert your needleupwards from back to front.

    Repeat on the right side.Find the first stitch on the bottom left, and insert your needle from back to front.

    Thread back through your first hole.Go back into the same hole as you originally inserted your needle through from back to front, and pull the yarn through. Great work: you’re ready to start your mattress stitch!

    Thread beneath the two bars.If you pull your knitting slightly apart you will see two horizontal bars. Take your darning needle and thread it beneath the two bars, pulling it through from front to back.

    Continue in the same pattern.Match the rows from each side as you zig zag from edge to edge for about 2 inches.

    Pull the thread up.Hold the base of the seam until the seam is joined and the stitches become invisible. Try not to pull it too tightly as you don’t want to distort your work.

    Continue to the top.Secure the ends by sewing them in. You should be left with a perfectly flush finish, and invisible seam line.

    Learn how to sew the Mattress Stitch for Crochet pieces with an invisible join, with this photo and video tutorial. No more worrying about the seam being shown.

    Do you remember the last time you wanted to sew together two crochet pieces for a cardigan, granny squares, blanket or a bag? And then you felt disappointed when you saw the obvious visible seam?

    Well, the Mattress Stitch prevents a seam from being seen. It creates an amazing invisible join between two crochet pieces. This technique also works great for knitting projects, but I’ll show you here how to do it for crochet.

    If you need to know how to weave in your ends such that they stay hidden, you should check outmy tutorialwhere I share some tips and tricks that I use all the time.

    As I’m hosting currently a Crochet Along for theAlphabet and Numbers C2C Blanket, we will be using the Mattress stitch in order to connect the stripes of the blanket. This tutorial is also ideal for theStriped Velvet CardiganI recently published.

    Now when you look at thecorner to cornerpiece (it’s actuallymini C2C) above you might think it’s just 1 piece, but it actually is two sewn together invisibly. Yes, you can’t even see that I used a blue yarn to sew them together! WOW! It’s like magic.

    Picture Tutorial

    First, if you prefer a video tutorial, make sure you scroll down to show you a more visual version of these pictures.

    Even though I used a different colored yarn to show off how to do the mattress stitch, I would still recommend you use the same color of yarn as the pieces you sew together.

    Next, you will look at the V’s on the sides/edges of your crochet and imagine “mouths”. When you sew the mattress stitch it’s like the “mouths” are touching/kissing.

    Step 1: Insert yourneedlewith your yarn through a V and then exit out of the neighboring V.

    Step 2: Now repeat the same process on the other crochet piece.

    Step 3: You will do this process back and forth between the two crochet pieces (like a zig-zag).

    Once you have sewn a few inches, you hold your 2 crochet pieces and then pull the yarn. That will close the gap between the two pieces and create an invisible join. You won’t be able to see the yarn that you used to sew.

    If you do not see a V, like the side of a stitch, you do the same technique, just that you imagine the stitch to be a V. You still sew on the edge/side of the crochet piece, no matter if you see a V or not.

    Now pull tight, fasten off and weave in your end. You should have a really tight and invisible join for the mattress stitch between the two crochet pieces.
