Just to play devil's advocate . . . there are many a quilter that prefer a cotton/poly blend. When making summer tops, I to prefer cotton/poly blends, because I don't like to iron! And don't forget all the t-shirt quilts, there is cotton and single knits joined together for these! So, as much as many of us now use 100% cotton, I really don't think the "Quilt Police" will be knocking on your door! lol!! Patty
