I did one demin/flannel rag quilt, and that was enough for me. I use old denim jeans in quilts, almost any pattern will do, as long as there are not areas where several seams come together (like a star). I agree that flannel on the back makes them pick up dirt and grass when used out of doors. But I like using flannel within a quilt. Here is one that I made recently, but don't have it quilted yet. I use a "crowsfoot stitch". I'll post something on it later. Anyway, I am making all my kids a picnic quilt, and here is one for my daughter. I used lots of flannel scraps that she had as sleep shorts as a teenager (like Taz and Bugs Bunny on plaid). S.
