For final sanding and rubbing out a finish, a good sanding block is essential. These final finishing steps require precision and flatness, and are always prone to accidental "cutting through" on the edges of a piece.

This post is about how to make sanding blocks for any purpose. It includes tips from my experience on how to outfit a sanding block for perfect results that are nearly fool proof.
