I made a jean quilt for my grandson about years ago. I used different shades of denim and cut into 6.5inch squares and arranged so that no 2 identical shades butted up, then stitched together and did some train applique on some of the squares.
Most importantly I did NOT use batting as it was very heavy but I did use flannel for the backing. He uses it still to this day.
