Mattress Stitch Crochet Seam Tutorial

Hi there crochet friend!

Today, I want to show you how to work my favorite seam type, the mattress stitch. It can be a little tricky and may take some practice, but once you get the hang of it, I think you’ll love it!

The mattress stitch is a great way to seam crochet fabric together in a way that’s almost completely imperceptible. Sewing the short sides of a rectangle together to make a hat? Joining granny squares for a blanket? Sewing the shoulders of a garment together? Sometimes seams are unavoidable, but they don’t have to be noticeable.

Set Up

Unlike other seaming techniques, where you sew your seam on the inside of your work, the mattress stitch is actually worked on the right side of your fabric. “Right side” refers to the side of your fabric you want people to see…the good side of your fabric if you will. Line up your two pieces of fabric with the right sides facing up. For this tutorial, I’ve got Piece 1 on the bottom and Piece 2 on top. Join your pieces together by threading the needle under the top ‘v’ of the first stitches of both pieces.

Psst! If you don’t know what I mean by the top V, see this post!

Two swatches are lined up one on top of the other, the bottom swatch is labeled "Piece 1" and the top swatch is labeled "Piece 2." Text reads: "With the fabric lined up and right sides facing up, join the ends together by threading the needle under the top 'v' of the first stitch of Piece 1 then Piece 2."

Following the photo tutorial is a video tutorial, just in case you need to see it in action.
