New style of crocheted potholder

I've made crocheted potholders for a long time, but at a Weavers Guild of St. Louis event on Sunday, I learned a new method. These are made in a similar way to my crocheted handbags, starting with a chain that forms the bottom edge and working around and around in a spiral. When the item folds diagonally to form a square, you crochet the inside edges together (I used a chain stitch). 35 stitches for the starting chain, using a Size G hook and Peaches & Cream 100% cotton yarn yields a two layer approximately 6 inch square potholder.
