Denim quilts were some of the first I made. I just cut them into 6" squares (I would probably do 6.5" nowadays), mixed and matched the different shades of blue and sewed together into a large throw size--almost twin size, and used a plaid as backing. I tied them. They are really cute. Still around. I made one with blues, one with blacks, one with oranges, greens, etc. (I started looking for used jeans/denim in various colors.)
