Crochet Basics: Thermal Stitch

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 winter crochet stitch, this is a great stitch! This stitch is as thick as TWO and is great for potholders, warm mittens or hats, and even casseroles! If you are looking for a way to add weight and warmth to a crochet project, you'll love this winter warmer. It's perfect for chunky projects like potholders or sturdy bags and baskets, and it's the coolest cold weather stitch you can learn. Are you ready to crochet the thermal stitch? Discover how to crochet the thermal stitch in this easy tutorial.


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

That’s it!

You can use the thermal stitch to make just about anything. The stitch creates a dense fabric that is not very forgiving, so I would stay away from wearable (like ponchos, etc) when using this stitch.


What basic techniques do you need to crochet the thermal stitch?

This can also be called the thermal single crochet stitch, because it is just single crochet, you just adjust where you place your hook.

If I’m making a pot holder using the thermal stitch, what type of yarn is best?

You want to pick a yarn that is not going to melt – so acrylic and yarns that like that are not the best. When making a potholder, use wool or the more common cotton yarn. Both of these are good choices because they can hold up to the heat.
