I used my mom's jeans in a memorial quilt. One tip: The seams will be FAT. Which means they'll be hard to quilt over. After I finished the quilt, I took a scrap piece of wood, put it on the floor, placed a fabric seam on it, put a double-folded piece of scrap muslin over it and pounded the snot out of it with a hammer. Just went down the rows of the quilt and did this. It took about a half-hour, but it really flattened the seams nicely without marring the other fabrics in the quilt, and I was able to quilt over them with no problem.
