If you crochet (or knit) for long enough, eventually you’re going to want to make something with seams. And while seamless patterns are great, seams can add a lot of structure, prevent stretching in the wrong places, and are important for the majority of motif projects. There are a variety of seaming techniques out there, but this tutorial focuses on the most invisible of seams – the Mattress Stitch! Here’s how it’s done.

The mattress stitch brings together two pieces of fabric, crocheted or knitted. The key is to mirror what you do on one side or one piece with what you do on the other. If you’re working into the top edges, as shown here, it’s easy to keep things even because each stitch is clear. If you are working in the side edges, then go through the same part of the stitch on each side when you can, and just watch your spacing and be consistent when you cannot. And here’s an important tip: when seaming a long section (particularly when working into the side edges), use stitch markers or clips to hold the pieces together in several places as you want them sewn, so you don’t end up with one side shorter than the other!
In this tutorial I’m using a contrasting yarn so you can see the stitches – but when you work this stitch for your project use a matching yarn for truly invisible stitching! This tutorial was made using Lion Brand Wool-Ease Worsted.
Step 1: Thread a yarn or tapestry needle with the yarn you’ll use for seaming – a long tail end is perfect if you’ve got it! Bring it through the first stitch from the wrong side of the fabric to the right side.
Step 2: On the opposite side or other piece of fabric, sew through the first stitch from the back to the front – mirroring the stitch on the first side.
Continue with the next set of stitches, working each side back and forth, sewing from the back to the front, or wrong side to right side, keeping it even.
After you’ve worked several sets of stitches, start tightening up the first few. And watch them disappear!
It even looks good from the back! Continue til you’re done – that’s all there is to it!
Seaming takes a bit of practice to be sure, but it’s an important skill to add your arsenal, and adds so many more patterns to the list of things you can make! When you use the same color of yarn to make the seam as you did for the fabric, it really does disappear. And the resulting seam is flat and nearly invisible! I hope you’ll give it a try!
