Santa Crochet Mason Jar Cozy – Free Crochet Pattern

Nothing says festive quite like a jar dressed up in Santa’s best! This crochet jar cozy makes the sweetest holiday gift wrap—just tuck in some cookies, candy canes, or even a tealight candle (in a glass jar for safety!) and you’ve got a handmade gift that’s equal parts fun and thoughtful.
The cozy slips right over a pint-sized Mason jar (16 oz), and the fluffy trim at the top gives it that perfect “North Pole” vibe. It’s a quick evening project and doesn’t take much yarn at all—so it’s stash-buster friendly too.
