The Toasty Thermal Stitch

There are so many beautiful and useful stitches out there it’s impossible to know them all, but the appropriately named thermal stitch is defiantly on the list of amazingly good to know. Especially if you need some extra insulation.

If you don’t live in a cold climate you might think you have no use for it, but I submit that this stitch is good for anyone that doesn’t like burning their hands!

There are two types of thermal stitch the single crochet and the double crochet. The thermal stitch in both cases is a one row repeat that is reversable which is always nice. It is a little bit fiddly when you first start the stitch and it is definitely going to take a couple rows to get used to the single crochet version.

Single crochet version

Is much better for smaller projects, it is rather expensive both in time and yarn. However, it is a beautiful stitch and you can’t help but be proud of the investment once you’re done.

Double crochet version

This version works up surprisingly quickly and is twice as thick and the single crochet version. It definitely seems to use less yarn and makes a wonderful squishy texture. If you’re wanting a garment or large project like a blanket I would definitely use this one for it. However it will take a lot of yarn and while the progress is definitely faster with this version it will take a while.

Why is it a time/yarn investment? Because you are essentially crocheting both sides individually.

Single Thermal Stitch Tutorial

These instructions are for a swatch.

Starting knot

Row 1. Make your starting knot and ch 11.

Chain and hook in first back ridge
Single crochet into the back ridge normally for the second row.

Row 2. Turn your work over and find the back ridge of the ch. You will work 1 normal sc into each of these. <10>

I find it easier to crochet sideways for the first few rows.
Second thermal stitch

Row 3. Do not turn your work. Ch 1, ins hook into the loop closest you and the fl from the ch row, pull up a loop, YO, pull through both loops. Repeat 9 more times. <10>

Row 4. Ch 1. Ins hook into the loop closest you and the Fl from the previous row, pull up a loop, YO, pull through both loops. Repeat 9 more times. <10>

Row 5- 11 repeat steps in row 4.<10> Once you can comfortably hold your work the higher side will be what faces you and you will work into the back of the rows. The top loop that you’ve been working into are back loops. The loops from the previous row that you pick up are front loops.

Row 12. This is a finishing row. Ch 1, ins your hook into both top loops and the Fl from the previous row, pull a loop through 3 loops, YO, pull through both loops. Repeat 9 more times. <10>

Cut your yarn and weave in your ends. The swatch is done!

It is very easy to miss the last stitch which is why you should count each row to ensure you have the right amount. This is what it looks like if you miss a stitch on the end.

To know how many rows you have count these dashes on both sides. They are highlighted in blue

You can make this stitch with any number of chains and as tall as you like. It makes a wonderful pot holder, the picture below is of one I made with 100% cotton yarn. I used Peaches & Creme in the color dark grey, you can use any color you like of course, but make sure you use 100% cotton because polyester and acrylic will melt in high temperatures.

To give some perspective, it took me over two hours to make. It is 21 stitches across and has 41 rows.

The normal craft store price for Lily Sugar’n Cream is $3.99 for 1 skein of 120 yards. If you just want one than a coupon can make it 2.39 with a 40% and 1.99 with a 50% providing there are no sales when you’re getting them.
