You're right. They are nice in Wisconsin. I have made two Queen size and numerous lap size flannel quilts. Tops and backs are all flannel. They were hand quilted (outline).
I am wondering if anyone has washed a finished queen size flannel quilt? I'm sure that my washer and dryer are not up to the challenge but I hate to think about a laundromat. I have washed lap size ones and they seem to do fine.
