Using old socks
Got old cotton socks? Cut the toes off and cut them along one side, then sew a zigzag stitch around them to use for cleaning rags. I've even used them as dishcloths. The tops make good sweat bands for cold drinks. Put the rest of the sock over your hand to dust with, or sew a piece of lace or ruffle onto the top and use as a personalized wash cloth in the shower. OR... sew velcro to fasten the top, then use up those soap slivers by putting them inside the sock.
