Hi: I use flannel and fleece together to make easy and comfy quilts. The flannel is the front (can be either one panel or pieced together) cut to any size you want. The fleece is cut 1" larger on all sides. Lines are sewn at intervals (5-6" apart) from the flannel side and once sewn, the fleece is folded over the flannel and becomes the binding. I hope this makes sense! I first learned this from an older Sewing With Nancy series and have since made many.
I also use flannel to make chenille scarves. Our sewing club has fabrics swaps and give aways and I just landed 4-5 yards of a cotton/wool flannel that made two beautiful scarves. I never would have used it for a quilt, but it turned out well as a scarf!
