My DD brought over two sheet sets she didn't want and said maybe I could find some use for them. In the past I would have taken them to the Salvation Army but not now. They make great backing for pot holders, place mats, table toppers, pincushions, and any other quilting project. I don't use sheets for quilt backing, yet. I have dozens of quilt backs in my stash. Cheap and Free, referring to cost, are two of my favorite words.
