Heres a clever way to fold a quarter sheet (or half sheet) of sandpaper
into a pad that eliminates the usual grit-to-grit contact. Whats nice about
this pad is the unexposed surfaces wont 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 dont 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.
