Thermal Single Crochet Stitch

You can use this stitch for almost any project that will benefit from the thickness and extra cushioning. Use it to make soles for crocheted slippers that will last longer and be softer or for super thick potholders that will give you extra protection from hot pans. Or even amigurumi projects – the double thickness of the crochet fabric ensures that you can stuff your piece full without it showing through or pulling out.

Follow these steps to learn the stitch. You’ll have a reusable makeup remover pad when you’ve finished!

One tip – count your stitches or use a stitch marker to mark the first st of each row. The fabric likes to scrunch down and can sometimes be difficult to see on the return trip.

How to Create the Thermal Single Crochet Stitch

Base Row: Start with a row of either 10 foundation single crochet, or make a chain of 11 and then work a row of single crochet into the chain, ch 1, turn.

Row 1: Work a single crochet into the back loop of each stitch across to end of row, ch 1, turn.

Row 2: On this row you will work into the back loop again but you will also put your hook through the leftover loop of the stitch directly below the one you’re working on, yarn over and pull the loop up to the level of the row you’re now doing, finish as a regular single crochet. Repeat across to end of row, ch 1, turn.

Row 3 and beyond: Repeat Row 2 until the piece is as big as you want it.

When you are ready to finish off the piece, work the single crochets in the last row through both loops of the current row and the leftover loop of the row below. This gives the piece a sturdy edge rather than having a row with those leftover loops hanging out there.

After working 1 row of tsc, you can see the loops left from working in back loop only.

Looking down at the top of the previous row you can see the tops of the stitched you just completed as well as the loops left over from the previous row.

Hook is through the back loop AND the loop left over from the stitch immediately below; ready to yarn over and pull through.

Thermal single crochet stitch increases and decreases are worked the same way you would work regular single crochet increases and decreases. The only difference is that your hook will go through the leftover loop from the previous row and the current stitch (or stitches) as directed by the pattern.

This stitch is used to make the Early Frost Mittens! Check out this pattern and make your own mittens in a tight thermal stitch for maximum warmth.

    I have used this stitch for hot pads…it works very well. But be sure to use all cotton also so the yarn does not burn easily.

    this looks like an easy-to-learn stitch but can’t find any patterns except the mittens to use it for like dish clothes or pot holders ??

      Make the foundation chain the width you would like your finished item to be, then follow the directions given. I think this stitch would be to thick for a washcloth and take too long to dry between uses, but it would make good hot pads and pot holders.

    Has anyone tried this stitch for a lap blanket for an elderly person ?

      I would think it may be too dense for a lap blanket. it would be warm though. Also, if you haven’t crocheted the thermal stitch before, it goes slowly and is hard on the hands after a while – at least that is my experience.

      It makes a very dense fabric that might be too heavy on the lap. You can try with a hook a couple of sizes larger than the yarn calls for. That would make a cushy fabric that isn’t as dense.

    I was wondering if this would make a good strap for a purse? Is it very stretchy? I am looking to change a strap and want something that won’t stretch out.

      From the designer: “Unless you crochet using fabric strips or some other fiber that doesn’t have any stretch (twine?), the strap would still stretch with this stitch. If you wanted the look of the crochet stitch, you could go ahead and make the strap and then line it with fabric (would need to be sewn to the underside of the strap). Depending on the purse itself, I’d probably replace the strap with vinyl, cork or even a chain.” Hope that helps!

      Yes it does! I’m currently making a thermal stitch backpack strap for my Lili bag ( outstanding crochet. Com) Much faster than the split single crochet.

        I’m also using the thermal stitch for my Lili backpack! I’m finding it really doesn’t stretch that much and the edges are very neat.

    Would this work well for a hot pad/pot holder? I’ve been making double-thick sc ones ‘in the round’. Do you think this stitch will be thick enough to make the equivalent of a double-sided single-crochet project?

      From the designer: “If you use a thick cotton yarn, and crochet tightly, this stitch might work for a hot pad? I would probably test that theory by making a small square and compare it to the double-sided single-crochet though.” Hope that helps!

      I’ve made all my hot pads for years. With cotten yarn and a size h hook.

    I think it would make a great change purse/clutch as wouldn’t have to line it.

    Zis this called single crochet or does that go into front of the row? Margaret

    • Nicola P.

      Hi Margaret, this is different than traditional single crochet, if that is what you are asking. Let me know if you have additional questions! – Nicola, Editor
