I saw this in some magazine years ago. To use a piece of sandpaper for sanding by hand, first fold a sheet into 1/4 sheet size (where the folds form a big +). Rip one of the folds to the center. This allows it to be refolded in a way so that a sanded side is always against the back of the sandpaper and not sand to sand, which wears it out pronto doing nothing. Sam
