Fold a quarter sheet (or half sheet) of sandpaper into a pad that eliminates the usual grit-to-grit contact. What’s nice about this pad is the unexposed surfaces won’t wear as you sand with the outer surface. The pad also works great when sanding a project on the lathe. With four layers of insulation, my fingers don’t get as hot.
To fold the pad, first make a single cut to the center of the sheet. Then follow the steps shown below. To expose a new surface, simply refold the pad.
