We use mason jars a lot around here as glasses, mainly because they seem to be the only glass my kids don’t break. I’ve seen a lot of fun things done with mason jars and decided a cotton cozy was in order. They work awesome! No more sweat running down the sides and as far as I can tell, it does insulate nicely.

These cozies work up fast and are easy enough for beginners. Make some to give as gifts or dress up a jar you throw your change in. Mason jars are great for a number of uses so have fun!

Pattern uses less than 50 yards of cotton.
