I have a system. Flannel sheets until they aren't so fluffy. Buy new sheets (lately have found like new flannels at the thrift store). Repurpose the old. I then cut the old flannels apart to 12.5 inch blocks, double layer, stitch together and they are our reusable papertowels until they fall apart. Haven't bought paper towels in a decade. Every couple of years I make a fresh batch. This set of twin sheets gave me 20 reusable papertowels. It's a great way of being a little bit more self sustainable.
