The Thermal Stitch crochet pattern has several uses – pretty much any pattern that requires lots of thickness and sturdiness is ideal for this stitch. Most crocheters like using this stitch for potholders or washcloths. But I used it for a pattern that you would have never thought would be great for it.

Thermal Stitch Crochet Pattern Uses

The first pattern I published using the thermal stitch was a book cover. Seriously, it was the perfect choice as it gave the book inside lots of stability and protection. Not only did it provide privacy by concealing what you are reading, but it also looked so amazing it made the book cover look like a real book.

The second crochet pattern that I published using this stitch was the Purple Passion Project Purse. I created many different purses and bags before. But I never liked the bag bottom being saggy or having to make a second layer with plastic canvas to provide stability. So I used the thermal stitch which made the bottom double thick and allowed me to save time and resources.

And of course, the stitch also looks great. Some crocheters who never have used this stitch before might want to be careful when it comes to counting the rows. As this stitch is made in a zigzag, all you need to do is count the visible rows on each side and add them up. That is all there is to it. Simple

Now, let me show you how to crochet this amazing stitch. Be aware I am showing you how to crochet it in a row only, but you can also simply make it in a round, but that is a bit more tricky. I would recommend making a flat piece and then sewing it together to make it into a circle.

Different Thick Crochet Stitch Types

Many crocheters have heard of the Thermal Stitch. But the stitch they assume is the only thick crochet stitch is the single crochet version of this beautiful zig zag technique to create a thick texture. However, you can crochet different thermal stitches using the same technique by crocheting in a zig zag.

In fact, I have created a Half Double Crochet and Double Crochet Thermal Stitch Tutorial for you as well. Furthermore, I wrote an article that explains and shows off many tips to crochet the Thermal stitch.

In fact, I have even invited a linked double crochet thermal stitch while teaching the double crochet thermal stitch to the members of my membership. That invited and ingenious crochet stitch tutorial can currently only be found within my membership called The Crochet Club. It’s incredible.

Start Foundation Single Crochet Row

1. Make a chain in the length needed and crochet 1 row of single crochet (in the back hum of the chains!), chain 1

2. Tilt the piece to the side. Now insert the hook into the back loop and the parallel loop from the chain row. Now do a traditional single crochet; repeat this for every stitch, chain 1 turn

3. Again insert the hook thru the back loop and this time the leftover loop (it was the front loop we ignored in the previous row) which is parallel to the back loop, crochet a traditional single crochet, chain 1

4. Repeat step 3 as long as needed

5. To finish the piece, so to crochet the very last row, insert the hook thru both loops and the parallel loop (from the previous row) so that you are going through 3 loops instead of 2 and crochet a traditional single crochet, sl st and fasten off and weave in the ends as needed

After finishing the last row, it should look like this:

If you need more help, check out the video tutorial above. This unique crochet stitch is double thick and made in a zig zag. Since that is very three-dimensional it can be hard to visualize in pictures. Therefore, I recommend watching the video tutorial for clear visualization of the thermal stitch.
