4 Ways for How to Seam Crochet Pieces Together

Seaming, some people either love it or hate it. As you crochet and diversify your projects, you’ll often run into crochet projects that are made in multiple pieces and have to be sewn together. For a long time I was afraid of projects with seaming because I never felt like I knew exactly what to do or how to seam crochet pieces together. If you’ve been afraid of seaming too, today I’m here to help! I’ve put together four different methods of seaming crochet pieces together, that will help you feel comfortable with seaming in no time.

The four methods in this tutorial are: the whip stitch seam, mattress stitch seam, slip stitch seam, and mattress stitch seam. The first two methods for sewing crochet pieces together involve using a strand of yarn and a yarn needle, and use basic sewing techniques to sew the pieces together. Methods three and four for how to join crochet pieces together use a crochet hook and strand of yarn, so if you’re not comfortable with doing any sewing than these two methods will be great for you. So let’s get to it!

4. Keep doing step 3 all the way up the rest of the edges to create stitch bars that go from one side to the other.

5. As you go, you can pull the thread tight every five or so stitches to tighten up the seam and secure the two pieces together. Then fasten off and weave in ends.

Method 2: Mattress Stitch Crochet Seam (or Invisible Join)

Mattress Stitch Seam

  1. Thread needle and turn crochet pieces right sides out. Insert needle up through the bottom right corner and back up vertically through the next stitch on the right side.
  2. Move needle over to the left side, and go up through the left corner and back up vertically through the next stitch on the left side.
  3. Go back over to right side and repeat step 1.
