How to Crochet: Make an Invisible Seam with the Mattress Stitch

The mattress stitch is a hand sewing method to join crochet or knit pieces together. But don’t worry, you do not need to be a seamstress to learn how to do it!

In fact, the mattress stitch is a very easy technique for seaming, and it works on a variety of pieces from granny squares to crochet and knit panels for garments.

Compared to other seaming techniques, such as single crocheting panels together, or slip stitching them with the zipper join, the mattress stitch has several advantages. Here are a few:

  • The mattress stitch is invisible, so it is great for joining panels of different colors.
  • The joining point is flat, so you do not have the typical bulky, ridged look of the other methods.
  • It works for joining both the top of the rows and the sides of the rows.
  • The mattress stitch uses very little yarn and it is very easy to learn.

In this tutorial, we’ll see how to do the mattress stitch using a couple of Simple Circle crochet squares as an example.

Mattress Stitch Seaming – STEP-BY-STEP TUTORIAL

Step 1

Cut an appropriate length of yarn and thread it through a tapestry needle.

I normally use at least three times the length I need to sew, or even more.

Step 2

With all right sides facing up, align the edges of the two pieces that you need to sew, and identify all the corresponding sts.

If needed, mark a couple of corresponding sts with stitch markers. This way, you can double-check that you’re not skipping any sts while sewing.

Step 3

On one of the two pieces, insert your needle into the back loop of the first st going from the back of your work to the front. Pull the yarn through until you only have a short tail left.

Step 4

With a movement from back to front, insert your needle into the back loop of the corresponding st on the other piece, and pull the yarn through (you do not need to pull very tight at this stage).
