I made a rag quilt using jeans on the front and flannel on the back. Used an 8" square so wherever it would fit I cut out a square. Bought most of mine at the Goodwill Store. Buy ones that have the wider legs, skinny jeans don't work unless you are using a very small block. You should be able to find it on here somewhere. I think I posted it under Denim Rag quilt maybe. Something like that.
