I use 2 squares of Warm & Natural batting, all the components need to be cotton; so that nothing melts when you pick up a hot pan. My potholders are a 7-8" square and batting and bottom fabric are 1" larger. For the top, its usually an orphan block or one that didn't come out right. I quilt the potholder diagonally and vertically and then trim and bind like a quilt, using a 2.5" strip folded in half; sew to the back and then turn over to the front and top stitch it down. I have made all of my pot holders.
