How to Sew Crochet Pieces Together Using the Mattress Stitch

Have you ever seamed two (or more) crochet pieces together, only to dislike the outcome? Have you ever wanted to join several pieces but are too intimated with sewing? Look no further!

This tutorial is for YOU!

Join Crochet Pieces With Mattress Stitch

The mattress stitch is my go-to way to connect most crocheted pieces, but I never even consider other technique when sewing garments.  This seaming method is also called the Invisible Seam. Not only is this virtually invisible, it's flat and doesn't pucker. 

This is my go-to to sew crochet pieces together! I want to convince you to make it yours!

Tips & Tricks When Using the Mattress Stitch

There's a few helpful hints when working this stitch but if you're anxious for the picture tutorial, click here

  • You can either cut a separate piece of yarn for seaming or you can use a tail.
  • Make sure yarn or tail is at least double the length you want seamed.
  • Use locking stitch markers to keep both pieces aligned evenly, which is recommended for larger seams. This ensures seaming will be accurate.  
  • Work with right sides facing. This ensures you can see exactly what the seam looks like as you're working it, and fix it if early enough if needed.
  • Pieces do not have to be laid next to each other. By putting the wrong sides together, you can work from inside to outside and get the same result. 
  • The Mattress Stitch can be use on stitches, raw edges, increases and decreases.
  • Garments that need to be seamed together are the easiest to alter for a more custom fit, like the Lacuna Pullover Below.

The Lacuna Pullover is a premium pattern that seams both arms as well as the sides.
