This pattern uses Helena's Potholder Stitch so I really won't be copyrighting the pattern since it's basically all that stitch.
Materials: One ball (2 oz) Peaches and Cream, Sugar and Cream or any other comparable WW cotton yarn.
Crochet hook size J
Ch 25 and work the above potholder stitch until the piece is roughly square. End off and hide any stray ends.
It should take less than a ball of yarn and you might even get two potholders out of one ball. If you were going to make a lot of them for gifts and such then you might want to invest in a 1 pound cone.
