Thermal Stitch Potholder Crochet Pattern
Last Updated on February 9, 2026
This thermal stitch potholder crochet pattern creates a thick double-layered fabric, which makes a great potholder. This double thick crochet hot pad pattern is made by working both into the stitch from the previous row, and the stitch one row below.
I promise it is not as complicated as you’d think! I put together a super detailed photo tutorial to help you conquer the crochet Thermal stitch to make these potholders!

The Thermal crochet stitch is one of the thickest crochet stitches. If you need to create a thick crochet fabric for your project, this is a fabulous option, which is why I chose it for making these potholders.
The crochet thermal stitch is made by working both into the stitch from the previous row, and the stitch one row below. You can use different stitches with this method, but for this crochet hot pad, I used the hdc thermal stitch.

The Yarn I Used For My Potholder
When making a crochet potholder, or hot pad, you should use 100% cotton yarn. The cotton is durable and resistant to high temperatures.
Since I wanted my crochet thermal stitch potholder to be extra thick, I used a Worsted (#4) weight 100% cotton yarn.
For the solid one in the photos, I used Knit Picks Dishie in Linen, and for the multi color I used Alize Cotton Gold Multicolor 57125 (sometimes it’s available on Etsy).
Materials
– Crochet hook 4.5 mm (I love the Tulip Etimo crochet hooks).
– Worsted (#4) weight yarn – I used Knit Picks Dishie in Linen, and Alize Cotton Gold Multicolor 57125
Amount of yarn needed: 50 gr / 87 m / 95 yds
Abbreviations (US)
ch – chain
sc – single crochet
hdc – half double crochet
Gauge – 17 sts x 17 rows = 4 in (10 cm) square
Finished Size – 6.5×6.5 in (16.5×16.5 cm)
Notes
- The thermal stitch is worked into both the back loop and the loop two rows below.
- It’s easier to work the stitch when the work is held at 90 degrees (as shown in the photos).
- The first 2 rows can be a bit tricky, but it gets much easier afterward.
- The pattern is reversible.
- This tutorial is made with hdc stitches, you can replace them with sc or dc and work them with the same method as shown below.
Crochet Thermal Stitch Potholder Pattern
Chain 28.
Row 1: work a single crochet into the back loop of the second ch from the hook, and in each of the chains across, don’t turn. Rotate the work in 90 degrees, as shown below. (27 sc)
Row 2: Ch 2, yarn over and insert your hook through back loop of the next stitch and through the back loop of the parallel stitch 1 row below (pics 1-2), yarn over and pull the yarn through 2 loops (pic 3), then yarn over again and pull the yarn through the 3 loops to complete a hdc stitch (pic 4).
Continue working across to the end of the row. (27 hdc)
* When you finish this row, there’s no need to turn (the work will be rotated in 180 degrees while you work the stitch, there’s no need to flip it to the other side), just keep the work as it is and repeat working in each stitch in the next row.
** We don’t turn, we are working into the wrong side.
Continue working row 2, until your potholder is 6.5″ (16.5 cm) tall. Then continue to row 3 to finish the work.
Row 3 (last row): Ch 2, yarn over and insert your hook through both loops of the next stitch and through the back loop of the parallel stitch 1 row below (pics 1-2), yarn over and pull the yarn through 3 loops (pic 3), then yarn over again and pull the yarn through the 3 loops to complete a hdc stitch (pic 4).
Continue working across to the end of the row.
Fasten off, soak and block if needed.
