I made a denim quilt for my son when he was 12. Used all of his worn jeans as well. I just made squares and added a sashing. (I was fairly new to quilting at that time.) I used an old blanket as batting and then a dark sheet for backing. It was a bit heavy but he absolutely loved it. He had it until he was 27 when his large dog decided he wanted the pillow underneath and went through the quilt instead of under it. The hole was as big as the pillow. After mending it several times he finally decided it was no longer worth keeping. If the hole hadn't been so big and almost in the middle I would have cut it down and saved what I could. I am thinking of making another blue jean quilt for him--he's 35 now and quite a bit more responsible. Good luck with yours!
