The same felt glides that keep scratches off wood floors keep pants on wood hangers. At the hardware store, look for glides measuring between 1/2 and 3/4 inch. Stick two glides onto each hanger, 3 to 4 inches in from each end and over the top of the rod. Hang trousers; they'll no longer slide around or fall into a wrinkled heap on the floor.
