How to Crochet the Thermal Stitch Photo Tutorial

The Thermal Stitch is one of the thickest, sturdiest, and warmest crochet stitches we can make. This stitch is effectively the thickness of TWO pieces of crochet, and is great for making pot holders, warm mittens or beanies, and even casserole carriers! Learn how to crochet the thermal stitch with this photo tutorial.

If you are looking for the thickest crochet stitch, this is it. If you are looking for the warmest crochet stitch, this is it. If you are looking for a heat resistant crochet stitch, this is a great one!

The thermal stitch is a simple variation of the single crochet. Instead of going through the two loops of the current row (the front loop and back loop), you’ll go through only the back loop of the current row and then the open loop from the row below it. Does that sound confusing? It’s really quite simple when you see it done. Let’s start!

Instructions:

1. Chain any number of chains. There is no multiple required for this stitch.

2. Starting in the second chain from the hook, single crochet using the back loop only. Complete to the end of the row. Chain one and turn.

3. Going into the back loop only of this row and the second half of the beginning chain (the loop you did not use) single crochet to the end of the row. Chain one and turn.

4. Again using only the back loop of the current row and the unworked loop from the row below, single crochet across.

Continue in this manner until the piece is as tall as you’d like it to be. When you’re ready to finish your work, you’ll need to crochet the following:

5. Chain one and turn, going through BOTH loops of the current row AND the open loop from the previous row (for three loops total) single crochet across.
