I have all my flannel fat quarters and yardage set aside to make a rag quilt (or two-I found a lot of flannel). I'm not sure if I want 2 or 3 layers-what do you think? with 3 I almost hate to "hide" some of the fabric in between but will 2 be enough for a decently warm quilt? I'll only be using it indoors, I think, and we keep it about 71 F in here during the winter.
