I've made about 35 raggy quilts. One with batting between two layers of flannel, about 25 with three layers of flannel, 5 with two layers of woven cotton with a layer of flannel in the middle, and a few with a mixture of flannel and woven cotton on the outer layers and flannel in the middle layer. My favorite? Two layers of woven cotton with flannel in the middle layer. But all come out fine.
