Another handy storage tip for organizing and storing sandpaper is to use an ordinary three-ring binder. Gallon-sized zip-lock bags are the perfect size for holding standard sheets of sandpaper. Simply use a three-hole punch to make holes in the edges of these zip-locks so they can be used like leaves in a notebook.
Moreover, how do you store sandpaper belts?
Sanding belts should be stored on a rack and sanding discs and wheels should be stored on/in racks, bins, drawers, or boxes. Improper storage can impact the safety of the abrasive, especially for sanding belts.
