Hopefully someone here has a solution to my problem. I have made a few chess boards and I am having a problem with the colors bleeding while I am sanding. The dark squares are gaboon ebony (I've also had the same problem with padauk) and the light squares are quilted maple (also curly maple). The dark dust from the ebony is staining the maple. Basically the dark dust is sinking into the light grain. How can I A: fix the problem now, and B: stop it from happening on future projects. The boarder for the chess boards has fine inlays of the same woods, so there is no way I can only sand the lighter wood only. Thanks in advance for any help.
