we have on old 1950's home with a major lack of storage. here is the easy solution i came up with to store washcloths and hand towels for quick access. all you need are a couple of storage baskets (these happen to be from pottery barn), a couple screws and a screwdriver or drill. just hold the baskets up to the wall, use a level to straighten and screw them right through the baskets into the wall. easy peasy.
