Mason Jar Cozies

I love mason jars! Any kind of glass jar makes decorating so easy and versatile. A great way to add texture and mix things up, is to crochet a cute and easy mason jar cozy. This is a quick project too. Less than 30 minutes (depending on how fast you crochet).

Things you’ll need to make a jar cozy:

  • Yarn in your choice of color/s
  • 5.50 mm crochet hook
  • A mason jar 

I used a 5.50 mm hook and my cozy is not super snug. If you wanted it to fit tighter then you can use a smaller hook. This jar cozy pattern works best on 16 oz jars but I do give you instructions on how to adjust it for a larger size mason jar.

Crochet Mason Jar Cozy Pattern

*Not everyone knows how to do a magic circle. They are easy once you have them figured out, but sometimes it can be a little tricky getting the hang of them. No worries. If you don’t have the magic circle down yet, just crochet chain four and join together. Then do 10 double crochets into the circle and close.

Start with a magic circle and chain 3

10 DC and close the magic ring ( 10 st )

Chain 3 and work 2 DC into each stitch around and slip stitch close ( 20 st )

Chain 2 and then HDC in first stitch and then 2 HDC in the second stitch. Repeat this all the way to the end and slip stitch close ( 30 st )

Chain 1 and DC in each stitch around ( 30 st )

Chain 1 HDC in each stitch around ( 30 st)

Chain 1 DC in each stitch around ( 30 st )

Chain 1 HDC in each stitch around ( 30 st )

Chain 1 DC in each stitch around ( 30 st )

Chain 1 HDC in each stitch around ( 30 st )

Chain 1 DC in each stitch around ( 30 st )

Chain 1 and SC in each stitch around and slip stitch close ( 30 st )

Chain 1 SC in each stitch around and slip stitch close ( 30 st )

Chain 1 SC in each stitch around and slip stitch close ( 30 st )

Chain 1 SC in each stitch around and slip stitch close ( 30 st )

And you are done!

How to Size up Your Crochet Jar Cover

Have a bigger mason jar you want to make a cozy for and need help? This crochet pattern is very simple to adjust. First, you want to go up a size or two for the hook.

Then, instead of stopping after row 9, add 5 more rows before doing single crochet. Just alternate between HDC and DC like the pattern does. When you get to row 14 slip stitch close and then add the 4 rows of SC stitches.


Different Uses for Crochet Mason Jar Cozies

Mason jar cozies are super versatile. Like I said before, they are perfect for adding color and texture to mason jar decor. I love the warmth the yarn cozy adds to the jar and your  home.

Once your jar is covered you can use it for tea lights, as a vase, or to hold things like pens or crochet hooks. We used our mason jar cozies this Thanksgiving to hold our cutlery on the table. Simple and cute.

Tons of people use mason jars as cups. You can also use your crochet cozies to collect the sweat that covers the outside of the jar when drinking something cold in the summer. Just use 100% cotton yarn so the excess water gets absorbed.

Once winter hits you can use your cozies to protect your hands from hot drinks like tea and hot cocoa. You can also use them when eating soup. They’re great for bringing soups to work. The jar cozy cushions the glass a bit for safer travels and then it protects your hands once the soup has been re-heated. 

These crochet cozies would make such adorable DIY Christmas gifts. Make the cozies in red or green and then fill the jar with cookie mix, hot cocoa, soup mix, candies or anything else you can think of. Tie a little gift tag around the neck of the jar and you’re all set!

Aren’t they cute? I love how they turned out. The great thing about crochet mason jar cozies are that you can do them in any color to match your home decor. You can also do stripes or one solid color.

Crochet jar covers are simple and sweet. They really are so versatile that you can put them around anything round really: cups, drinks, tin cans. The sky’s the limit.

Have fun and be sure to show us what you’ve made.

    1. The chain 3 is totally separate step. It does not count as part of the stitches in the next step. Hopefully that helps! Let us know if you have any more questions.

  1. I am looking for a pattern for a 64oz wide mouth mason jar cozy and am completely brain-dead when it comes to adjusting a pattern. Can you please help me?

    1. The best thing to do is to keep adding a chain each round until the base is the same as the jar. Then keep that number until it’s almost as tall enough for the jar. Then try a single stitch crochet for the last few rows until it’s the height you like. Hope that helps.
