Crochet Mason Jar Tumblers & Coasters

Crochet mason jar cozies are a quick way to dress up jars for gifts or seasonal décor. This pattern creates a textured cover that can be used on a small jar or a mason jar tumbler. Choose a jar size before you begin so you can check the fit as you work.

The finished cozies can also decorate jars used for homemade jams and jellies, pens, or small plants. If you plan to use a cozy near a tealight, keep the yarn well away from flame and heat; an LED tealight is a safer decorative option.

Materials and stitches for crochet mason jar cozies

• Sport or DK-weight yarn. Wool or acrylic yarn is suggested because it stretches more readily than cotton.
• 3 mm crochet hook.

Abbreviation: inc means a double crochet increase: work 2 dc stitches in the same stitch. Ch means chain, sl st means slip stitch, dc means double crochet, and sc means single crochet.

Check your tension and the width of the jar after the base rounds. A flexible fit is helpful when putting the cover on or taking it off.

A set of these clover-shaped coasters is a thoughtful handmade gift. To help them keep their shape and lie flat, spray them with water and pin them to an ironing board in the desired shape. Let them dry overnight before removing the pins.

Make a set for someone who enjoys coffee or tea. The mason jar cozies can also be used with jar tumblers. — Holly
