I have made a couple blue jean rag quilts for a quilt raffle for a dog rescue that I am a volunteer for. I named them after my two Minpins. One is called the "Jasper Ragster" and the "Baxter Ragster". Easy and fun to make to use up some of your jeans. I put flannel on the back for softness. I don't know about stretch jeans; I didn't use any.
