Stir up a super wood filler
Because wood putty never seems to exactly match the wood, patches stick out like a sore thumb. For an exact color match, there's nothing closer than the actual wood. Gather fresh sawdust--the finer the better--from your belt sander or workbench. On waxed paper, stir the sawdust into a puddle of epoxy. Fill holes, cracks, and mistakes with the mixture.
