My first posting. I use flannel a lot for the backing of blankets and quilts. I piece the top using blocks and embroidery and just use the flannel as the backing. I live in Houston and the flannel gives just enough warmth without being too heavy. I usually use a stitch in the ditch method or fun and done and the flannel works great. I have also done some echo quilting around the embroidery designs. I always wash my flannel before using it. Good Luck.
