We’ve recently stopped buying bottled water, and bought a pitcher to filter our water instead. I have reusable bottles for water, but honestly? When I’m just hanging around the house, I prefer a pint jar. The water seems to taste cleaner out of the glass, to me.

Then we were at Starbucks the other day, and I saw a glass water bottle sheathed in some sort of plastic or silicone, to be less breakable. So I thought, why can I not make a cover for my humble canning jar, so it can go places with me? And the idea for a water jar cozy was born.

To make your own, you will need about an ounce of worsted weight cotton yarn, a size F crochet hook, and a hair elastic.
