Over time my calloused feet rubs the threads creating little balls on the sheets, eventually making the sheets scratchy instead of soft. Last night I decided to try something I'd heard about for sweaters with this problem. I took my razor and I shaved my sheets. No shaving creme needed! It worked marvelously! I can hardly believe it was so easy. A few years ago I purchased one of those fancy shavers for sweaters and it did absolutely nothing so I had given up. But using a regular old razor did the trick. I had to clean the fuzz out of the razor every few strokes, but that is no big deal. Sweaters and sweatshirts, watch out, here I come! In the meantime, I really should get a pedicure.
