I still have a denim quilt I made for my kids when they were tiny, and my oldest is 30. The quilt was made from old jeans and it still looks as good today as it did when I first made it. I cut about 6" squares and backed it with a red cotton print. No batting. I didn't even use binding; I just put the top and back together (right sides together), stitched around it, and turned it. I topstitched diagonally through the blocks with red thread to hold it all together. It was super easy to make and it's lasted through three kids dragging it around inside and outside.
