I don't make many bowls, but found a piece of walnut with some sap wood that had broken off a live edge slab when I went to a local hardwood store. I bought a few other boards and he gave me this piece free since the slab had already been paid for. It's maybe 2-1/2" thick so I thought I would make some little bowls. Overall, I'm happy with it, though it could have used a little more sanding under the lip. Aussie Oil friction polish. Pen shown for size.
