For the longest time, I used a scrap piece of wood for a sanding block. It was simple and did not cost much. But it never worked as well as I would have liked, the sandpaper tended to shift around and tear. Recently, though, I came up with a new sanding block that works really well. Not only is it sized to fit my hand perfectly; it also holds the paper in place using plastic tubing.
