Free Crochet Pattern Jar Cozy
These very modern looking jar cozies are crocheted in the blocked puff stitch. You can use the jar for a candle or as a vase. The jar cozy is made with Katia Seacell Cotton yarn, which (I know it sounds weird) contains seaweed and is biodegradable.
You can find the free crochet pattern of this Jar Cozy on the website of Crochething.
