A few weeks ago I made this drawing for a little cabinet with live edges. A very generous member whom I won't name (thanks very much, Larry) sent me some walnut with a live edge. The slope on the edges is much shallower than in my drawing which is fine but there's some neat little details--bumps and things like that which I want to keep. I want to sand off the remains of the bark and smooth the edge so it is pleasant to touch so I'm looking for suggestions for a sanding device. I started out sanding by hand and thought about backing the paper with a sponge of some sort but that won't help me get in around the details. What have you used that works?
