The boo looks perfect, Eric. But just remove the edge on top of the nodes. Just lightly sand it now with 320 and only length wise along the limbs. Don't even be concerned about the little bit of rind in those longitudinal depressions. After you stain the boo, those long depressions will give the boo character... An area to pay attention to is on each side of the nodes, above and below it. There will be scratches there, I guarantee it. Just use your thumb or finger and sand those areas carefully. What I do is apply a light coat of stain to the bow, when you do that, all the little tiny nicks and scratches will pop, right out at you. I then just sand those scratches out and stain again. I use an alcohol based aniline die, and touch up after sanding out scratches is a piece of cake, it just blends in so nice.. Reason being alcohol based stain evaporates very quickly, like in 20 seconds. A water based stain takes a lot longer and the water raises the grain on the wood, alcohol based stain does not raise the grain of the wood.
That will be $19.95 for advice:) LOL
