Learn how to sew the Mattress Stitch for Crochet pieces with an invisible join, with this photo and video tutorial. No more worrying about the seam being shown.

Do you remember the last time you wanted to sew together two crochet pieces for a cardigan, granny squares, blanket or a bag? And then you felt disappointed when you saw the obvious visible seam?

Well, the Mattress Stitch prevents a seam from being seen. It creates an amazing invisible join between two crochet pieces. This technique also works great for knitting projects, but I’ll show you here how to do it for crochet.

If you need to know how to weave in your ends such that they stay hidden, you should check out my tutorial where I share some tips and tricks that I use all the time.

As I’m hosting currently a Crochet Along for the Alphabet and Numbers C2C Blanket, we will be using the Mattress stitch in order to connect the stripes of the blanket. This tutorial is also ideal for the Striped Velvet Cardigan I recently published.

Now when you look at the corner to corner piece (it’s actually mini C2C) above you might think it’s just 1 piece, but it actually is two sewn together invisibly. Yes, you can’t even see that I used a blue yarn to sew them together! WOW! It’s like magic.

First, if you prefer a video tutorial, make sure you scroll down to show you a more visual version of these pictures.

Even though I used a different colored yarn to show off how to do the mattress stitch, I would still recommend you use the same color of yarn as the pieces you sew together.

Next, you will look at the V’s on the sides/edges of your crochet and imagine “mouths”. When you sew the mattress stitch it’s like the “mouths” are touching/kissing.

Step 1: Insert your needle with your yarn through a V and then exit out of the neighboring V.

Step 2: Now repeat the same process on the other crochet piece.

Step 3: You will do this process back and forth between the two crochet pieces (like a zig-zag).

Once you have sewn a few inches, you hold your 2 crochet pieces and then pull the yarn. That will close the gap between the two pieces and create an invisible join. You won’t be able to see the yarn that you used to sew.

If you do not see a V, like the side of a stitch, you do the same technique, just that you imagine the stitch to be a V. You still sew on the edge/side of the crochet piece, no matter if you see a V or not.

Now pull tight, fasten off and weave in your end. You should have a really tight and invisible join for the mattress stitch between the two crochet pieces.
