How to Crochet the Thermal Stitch + Video Tutorial

Have you been searching for a thicker, not-so-holey crochet stitch??? Then you have found the perfect stitch. The Thermal Stitch is perfect to make pieces that need to be thicker (but not too heavy) sturdy fabric and not have little holes all throughout the piece. It’s super stretchy and actually a very simple stitch to make.

It makes the perfect stitch to use for blankets and scarfs. It even is a great stitch for pot holders when made out of cotton yarn to set hot pans and dishes on like THESE CROCHET POTHOLDERS!

Is the Thermal Stitch a Hard Stitch?

NO! It’s a very simple and easy stitch to do. If you know how to chain and single crochet, then you can do the thermal stitch. You will just be placing your stitches in a little different spot than normal and it creates a dense fabric that has a thick texture.

Can the Thermal Stitch be made with other stitches?

Yes! This is the most common thermal stitch, I think, using the simple single crochet. It’s also known as the Thermal Single Crochet Stitch. You can easily substitute either double crochet or half double crochet in place of the single crochet.

The thermal crochet stitch is made with basic crochet stitches, you just need to know the difference between the front loop of a stitch and the back loop of the stitch.

It’s made with a 1 row repeat row after the 2nd row, it’s such an easy stitch to crochet! You can also start with any number of chains that you would like, it doesn’t have to be a specific number of stitches.

Thermal Stitch Pattern

You can use any weight of yarn and corresponding crochet hook that you want.  For this tutorial, I’m using a worsted weight #4 yarn and a hook size 5.50mm / I.

Step – by – Step

Row 1: ch any amount of stitches plus 1 extra st for the turning st, t and work a sc in the second chain stitch from your hook and in each ch st across

Row 2: ch 1, t, work a sc in each blo of each st across

Row 3: ch 1, t, work a thermal sc in each st across

th sc = Thermal single crochet (insert hook into the back loop and into the front unworked loop of the stitch from the row below (previous row), yarn over and pull up a loop, you should have 2 loops on hook, yarn over pull through both loops on hook)

Next row and beyond: continue repeating row 3 until you reach the desired length.

Last row:  You can finish the very last row by working a single crochet in each stitch across and inserting your hook through both top loops and the front loop that is unworked from the previous row.  You will inserting your hook through 3 loops on the final row.

And that is all there is to the Thermal Stitch! I hope that you will make many projects with this stitch!
