Thermal Stitch Crochet Ideas and Patterns

If you need a super sturdy stitch with virtually no holes, crochet thermal stitch is the answer. It creates a double-thick texture, perfect for various home accessories, all while using basic crochet stitches! Beginners and experienced crocheters alike, dive with me into the world of this clever technique and see what you can use it for.

Ready? Let’s go!

How to Crochet Thermal Stitch

This crochet stitch combines the back-loop-only technique with single crochets.

You start by working one row of single crochets, and another of single crochets in the back loop. However, in each next row, you go through both the back loop and the loop from the row below. This creates double thickness and makes the project very sturdy.

Ashley explains it beautifully in her tutorial on hearthookhome.com.

Where to Use Thermal Crochet Stitch

This stitch’s unique qualities make it perfect for kitchen accessories, such as potholders, hot pads, and more. When choosing these patterns, remember to use 100% cotton yarn. Acrylics will melt when in contact with heat! Learn more about yarn types in my article 🙂

In the roundup section, you will also see projects like blankets, coasters, or bag straps.

I link free crochet patterns and resources below the pictures whenever possible.

The Best Thermal Stitch Crochet Ideas

Thermal Potholders with Linen Applique by Kolorowo Owocowo

How do you turn a potholder into a truly unique project without making it complex? By choosing the right colors and adding eye-catching details. The crocheter behind Kolorowo Owocowo decided to hand-sew a piece of embroidered fabric on top. Clever!

Multicolored Thermal Potholders by Shani

Choose multicolored yarn for quick and tidy color changes without any ends to weave in! I love seeing how the hues go together, creating unexpected compositions. No matter if you go for a juicy palette or a subdued color combo, such potholder will look fantastic. Oh, and you don’t have to worry about stains – they will go missing among colorful spots.

Thermal Coasters by Olga Vogel

Use up leftover yarn ends and make colorful coasters. I’m in love with the idea of using thermal stitch for this project, because many coasters are too flimsy for me! These ones are both practical and elegant – thick enough to keep the heat away from the table, but not compromising on style.

Crochet Thermal Stitch Potholders by Lisa and Camilla Henriette

Stripes and color blocking are one of the easiest ways to make “boring” projects more exciting. Choose the colors you truly love and experiment with color order and stripe thickness. To make thermal potholders even more useful, add a small loop in one of the corners for hanging purposes.

Two images show crocheted thermal stitch pot holders. The first set features striped patterns in reds and oranges; the second set has two-tone yellow and orange designs with loops for hanging.

Double Thick Potholders by Ashleigh Kiser

I’m a big fan of soft pastel colors, so these potholders by Ashleigh are one of my favorites. A set like this will look lovely in any kitchen, and that makes it a fantastic gift idea. Remember that you can easily adjust the size of these potholders by changing the number of stitches you start with.

Rainbow Thermal Stitch Potholders by Pia Wester

Multicolored yarn offers quick color changes and results in colorful dots, but self-striping one creates long lines of the same color. Pia used mini-skeins to make the potholder in the photos, but self-striping yarn will provide a similar effect. Learn how to change colors in crochet with my article!

Crossbody and Bag Strap – Thermal Stitch by Anna Burton Designs

Anna’s concept is ingenious, because is there a better stitch for a bag strap than the thermal stitch? It’s sturdy, elegant and has a nice clean edge. As you can see in the photo, you can make a bunch of removable straps in various colors to add some variety to your everyday errands.

Thermal Stitch Temperature Blanket 2018 by Marcia Libby

Are you familiar with the concept of temperature blankets? Each row corresponds with the daily average temperature and is represented by a specific color. While the most popular choice for this blanket type is the moss stitch, Marcia went for the thermal stitch. I can imagine this throw being comfortably heavy and super warm!
