Even denim can wear out. My mom made the oldest grandsons quilts from denim one christmas. When they graduated the quilts were pretty much in pieces because they went everywhere with the boys. They all loved them. She made squares pieced randomly on the top and had a handkerchief backing. She since has made new ones for the ones who requested them and gave her jeans. Those she mixed with cotten, left some pockets on and if they were a namebrand jean she added that label. They are pretty awesome.
