Single Crochet Thermal Stitch | How to Crochet

The Single Crochet Thermal Stitch creates a fabric that is double thick! It is a stitch that lends itself well to a variety of items!

Although the stitch is double thick and quite dense, it has quite a bit of stretch to it. So along with projects such as pot holders and blankets, I have also seen this stitch used in hats and headbands.

There is a trick to this stitch! It is a simple single crochet stitch however the stitches are worked through the back loops of both row worked one and two rows below. If this sounds confusing, don’t worry, there is a video tutorial below that will help you on your way!

If you enjoy this stitch tutorial, you may want to check out some of the other tutorials on my blog such as Crossed Double Crochet | How to Crochet. You can find many others under the “crochet stitches” tab on the menu and a new one is added every Sunday!

Materials:

For this tutorial I will be using the Caron x Pantone yarn by Yarnspirations along with a 6 mm crochet hook.  The hook shown here and in the video below is a wooden streamline hook by Furls Crochet. However you may use any hook and yarn combination you choose.

Single Crochet Thermal Stitch

This stitch is worked in rows in this tutorial.  At the end of each row you will need to chain 1 and turn your work.

Don’t forget to check out the free video tutorial linked below!

To begin, make a slip knot and then chain your desired number of chains.  For this stitch pattern you can use any number of stitches plus one for your foundation chain.

For my swatch I will be making a foundation chain of 21 chain stitches.

Row One:

When you look down at the top of your foundation chain, you will see a chain of V’s. For the beginning of this stitch, you are going to work in the back loops only of your foundation chain. The back loops are the horizontal bars of the V farthest away from you.

So, working in the back loops only, work a single crochet in the second chain from your hook and in each chain across.

At the end, ch 1 and turn your work.

Row Two:

Now you will work into the back loops of both the row just worked and into the foundation chain below. Insert your hook in the back loop only of the single crochet and of the chain stitch of your foundation chain below. Complete your single crochet stitch. Repeat this all the way across.

Chain 1 and turn your work.

Row Three:

Row three is worked the same as row two however this time you will be working into the back loop only of the row below and the row two rows below.

And that’s it!

Repeat this third row for the desired length of your project.

To Finish your square:

To finish your square you are going to work one final row of single crochet stitches. This time when you work across, insert your hook under both loops of the top row AND the back loop of the row two rows below. This means that you will be inserting your hook under three loops.

At the end, fasten off and weave in your ends.
