This pot holder is super thick, thanks to the thermal stitch AND the extra pockets on the back.

They give you the option to use it almost as an oven mitt, or lay it on the counter as a regular pot holder. Yay options!

Since fall is in the air and the holidays are coming, it’s the perfect time to add a few pot holders to your project line up. Plus, you can learn the awesome thermal stitch!

For this pattern, I just used one strand of cotton yarn. If you want to make it even thicker, you could double it up and use two strands. It’s up to you! One strand was plenty thick for me.

What is the thermal stitch in crochet, anyway?

The thermal stitch is a simple crochet stitch that makes a double thick crochet fabric. It’s almost as thick as two layers of single crochet stacked together, but with half the work!

I’ll show you how to do the single crochet version of the thermal stitch in this tutorial. You can also do the thermal stitch with half double and double crochet.

Supplies You’ll Need to Make a Double Thick Crochet Pot Holder

How to Make this Double Thick Crochet Pot Holder Featuring the Thermal Stitch

Step 1: Make the foundation chain

Chain 25 and then turn.

single crochet into the back bump of the chain

Flip the chain over so the back side is facing up, and you’re going to single crochet into the back bump of the second chain from your hook.

Continue single crocheting in each chain across. You’ll have 24 stitches all together.

Step 2: Crochet the first single crochet section

At the end of the first row of single crochet, chain one, turn and single crochet in each stitch across.

Repeat that until you have 16 rows of single crochet.

Step 3: Prepping for the thermal stitch

Now we need to do the first preliminary row for the thermal stitch. Single crochet in the back loop only of each stitch across, chain one, and turn.

Step 4: How to crochet the thermal stitch

crocheting the thermal stitch rows

Now for the actual thermal stitch. Insert your hook into the back loop, and then insert it into the leftover loop from the previous row (it was the front loop that you didn’t crochet into).

Now make a single crochet and you’ve completed your first thermal stitch!

Continue thermal stitching all the way to the end of the row, chain one, and turn.

Repeat this for 42 rows (you’ll have 43 rows of thermal stitch all together).

After your 43rd row of thermal stitch, make 16 more rows of regular single crochet.

After the last row, slip stitch in each single crochet across to make it a bit less stretchy.

Step 5: Sewing it all together

Now you’ll want to fold the single crochet flaps inward so we can sew it together.

There will be a ridge of loops on one side from the last row of thermal stitches. Be sure that side is on the inside so it won’t show.

I used a tape measure to make sure my sides were even. It never hurts to check!

Pin the sides in place before you start stitching.

whip stitch the edges of the folded pot holder

Thread some of your yarn onto a large eye needle and whip stitch along both edges.

Weave in all your ends and your double thick crochet potholder is ready to go!
