This waistcoat stitch jar cozy crochet pattern is a great way to practice a stitch that looks like knitting.

Waistcoat stitch makes a really thick fabric, so it’s perfect for protecting your hands. I love the idea of using it for a hot pad, coffee mug cozy, or, in this case, a jar cozy. I have options for large and small jars and you can use them for all sorts of things.

Supplies for Jar Cozy

This waistcoat stitch jar cozy is a great stash buster, too, because it doesn’t take much yarn or much time to make.

The small version uses about 25 yards of yarn, while the larger one used 34. Both are made with Red Heart Super Saver yarns.

The small one use a couple of colors from a jeweltone stripe skein of Super Saver O Go, which I cut apart so the stripe would end at the end of a round. The larger version with a patriotic twist uses regular Super Saver in Cherry Red and Royal. The white is Mary Maxim Starlette in white, because I happened to have it handy.

Any worsted/medium/weight 4 yarn will work for this project.

In addition you’ll need a US K/10.5/6.5mm crochet hook (I love Susan Bates hooks for waistcoat stitch because the end is a little pointy, which makes it a little easier). If you’d like to use a stitch marker to mark the beginning of the round, grab one of those, too.


This is such a small project it’s not worth it to make a swatch, just measure your project once you’ve worked about an inch/2.5 cm and adjust if necessary.

I got 3 stitches and 4 rows per inch/2.5 cm.


The smaller waistcoat stitch jar cozy in 10 inches/25 cm around and 2 inches/5cm tall. It’s to fit a pint sized wide mouth Mason jar.

The larger one is for a quart sized wide mouth jar and it measures 12 inches/30.5 cm around and 3 inches/7.6 cm tall. You can make them longer if you like.

How to Make a Waistcoat Stitch Jar Cozy

For the small size, chain 30. For the larger size, chain 35.

Slip stitch to join the last chain to the first chain, being careful not to twist. Add a stitch marker if you like.

Work a single crochet in each stitch around.

Begin working wasitcoat stitch in the round, working into the center of the v of the stitch below. The place you want to work is where the needle is pointing.

You can work in a single color or make stripes. My small version has four rounds in each color, while the larger one has five rounds each in red and blue and two in white. Here’s how I change colors in crochet.

When project is your desired height, fasten off and weave in ends.

Using a Jar Cozy

I happen to have a cup lid for a small Mason jar, so the small waistcoat stitch jar cozy is perfect for protecting my hand when I’m drinking coffee or keeping off condensation when drinking something cold.

These would be a great way to jazz up storage jars on your desk or shelf, and I think they’d add a nice bit of extra cuteness when you use your jars as flower vases. Especially that red, white and blue one gives you an instant on-trend centerpiece for any patriotic holiday.
