Very basic cozy for a wide-mouth pint canning jar. Knitted with Lion Homespun yarn in the pictures, but anything that will get about 3 stitches to an inch on size 10 needles will work.

The holder has 2 rows of K1/P1 ribbing on top and bottom and 3 columns of seed stitch up each side. The main part is knitted in Stockinette and there are 2 buttonholes on one side.
