Single Crochet Thermal Stitch

Share this idea!

The single crochet thermal stitch creates a solid, dense and very warm textured pattern that is ideal for pot holders, hot pads, warm blankets and mittens.

Single Crochet Thermal Stitch

I discovered the single crochet thermal stitch after crocheting potholders using the lemon peel stitch. When I made my potholders, I essentially crocheted two dishcloths and then placed them wrong sides together and single crocheted around the outside edge. They made for some really lovely potholders, I might add!

But it got me to thinking about other stitches that I might use to create potholders. Or maybe simply using the lemon peel stitch with two strands of yarn instead of one.

Although I did find several tutorials and patterns for the single crochet thermal stitch, they all left me confused. I especially, for some reason, had a hard time understanding how to begin and end the stitch when working it in a pattern, like if I wanted to crochet potholders.

With enough practice, I can say I fully understand how to crochet this stitch! Hopefully, I can explain it well enough for you to give it a try, too.


Before you begin practicing the single crochet thermal stitch (scts), there are just a few supplies you’ll want to have on hand:


ch = chain
sc = single crochet
scts = single crochet thermal stitch
st = stitch
yo = yarn over
blo = back loop only
flo = front loop only

How to Start the Single Crochet Thermal Stitch (scts)

The first thing you should know about the single crochet thermal stitch is that it is abbreviated scts.

Also, the scts is often worked with two strands of yarn held together and worked as if it was just one strand. For practice sake, you might want to grab your favorite chunky yarn and crochet hook, if you don’t want to work with two strands of yarn to practice the scts. In the pictures below, I’m using two skeins of Lily Sugar ‘n Cream yarn held together.

Foundation Chain

For the foundation chain, you simply chain any number. Since we are just practicing this stitch, I recommend a chain of 10 or 11 stitches. You can make your swatch bigger, if you want.

Step 1:

Working in the back humps only of the ch, insert hook into the 2nd hump from the hook, yo, pull lop through hump, yo, pull yarn through both loops; single crochet made. Single crochet in the back hump of each ch st across.

Step 2:

When you reach the end of the row, ch 1 and hold your work so that the front of the row you just finished is sort of facing you, like pictured in the photo on the right below.

Normally, when you are crocheting rows using single crochet stitches and you reach the end of the row, you would chain 1 and turn your work so that you are working with the back of the previous row facing you. It is actually easier to work the first few rows, at least, if you hold the work as pictured below. It will make more sense as you work this stitch – I promise!

Step 3:

Insert hook into blo of sc from previous row and into flo of the sc from the row below the previous row. (These loops should be obvious if you are holding your work as pictured.)

Step 4:

YO, pull yarn through booth loops, so that you have two loops on your hook, yo and pull through both lops, scts made; scts in each st across.

When you reach the end of the row, ch 1 and repeat Step 4.

Single Crochet Thermal Stitch Video

This stitch is more of an intermediate level stitch and it took some practicing for me to get the hang of it and fully understand how to achieve this beautiful crochet stitch. So, hopefully, this video will help you, too.

Here’s the short version of the video:

Some Tips

Tip #1: Practice

Like I said, the single crochet thermal stitch was a little hard for me to follow at first. But, persistence (some call it stubbornness) and determination paid out. I now completely understand what’s going on with this stitch and how to work it.

Grab your yarn, crochet hook and practice!!

Tip #2: Stitch Anatomy

Essentially, what’s going on with this stitch is that you are crocheting over the outside of the stitch. You’ll see what I’m talking about when you crochet a few rows. So, what you see on the outside of the stitch is what’s normally on the inside of a stitch.

Tip #3: Last Stitch

Also, when you get to the last stitch of the row, the back loop of the stitch has a tendency to hide under the chain stitch, so you might have to kind of move the ch stitch out of the way to grab that last loop.

Tip #4: Not Easy on the Hands

I should also say that this stitch is not the easiest stitch to crochet. If you have arthritis or stiff joints, you might find the tight weave of the stitch a little tougher on the hands.

Tip #5: Watch the Video

Again, watch the video and hopefully this will all make perfect sense. As always, if you have any questions, please don’t hesitate to ask.

Happy crocheting!!
