Today I share the pattern of my thermal potholders with you. The thermal stitch works very addicting, so don’t say I haven’t warned you. It is such a beautiful, thick and yet flexible stitch. It is perfect for potholders and coasters.

When you work the first 3 rows, you might wonder how it is ever going to look like a potholder. But once you proceed to crochet, you will get the hang of the stitch and see how stunning it is.

The size of my potholders is about 18×18 cm (7×7 inch). It is easy to increase or decrease the size of the potholders by adding chain stitches (divisible by 1) and more rows.

I used a larger crochet hook than indicated on the wrapper of the yarn, this will make your potholder more flexible. It is important to crochet evenly, it will show sooner when you crocheted a part more tightly. Measure your work while crocheting. You don’t want to end up with potholders that are too small.

Chain 36 with crochet hook 4.0 mm. The last chain is your turning chain

Row 1
1 single crochet in second ch, 1 single crochet in each of next chains, turn (35)

Row 2 to 64
ch 1, 35 thermal stitches (see video above), turn. Note: Keep a close eye on whether your potholder becomes neatly square. You can always add or leave out a few rows)

Row 65
chain 1, 34 thermal stitches, (change to hook size 2.5 mm) chain 15, 1 slip stitch in the last stitch. turn.

Row 66
chain 1, 20 single crochet around the loop. (change to crochet hook size 4.0 mm), now you will work the thermal stitch again, but in a slightly different way. You will work through the entire stitch and through the loop at the back. I explain this in the video above.

Have fun with your new potholders!
