We had a neighborhood "quilt for charity" group for about 8 years, and we used jeans for quite a few quilts, and also made quite a few "funky" bags also. We used flannel to accent some, and I did a big one using long strips instead of squares, with pockets sewn on the 4 corners. I still have one in mind that I want to do using some eyelet curtain trim (also recycled, of course, like the jeans), but it's still on the "do later" list.
