Ever since I started ml and pipe smoking for that matter, I have come up with great ideas, just a few hundred years too late. This might not work with raised carving as you woulndn't want to blur your lines. After I have done the first sanding I put on a light coat of stain. This makes any scratchs show up real quick. As the wood is white and the scratchs are light this makes it a lot easier for me to see. Sometimes I don't see the scratch until I've sanded the stain around it. Any one else try this?
