So when I make the flat pieces, I do an initial carving and it’s easy to get all of the big chunks out. However, I go back over each hole and cut more out to round the sharp edges, make it thinner, and to enhance the design. When I do that I end up with all of these tiny little pieces stuck in the holes. They drive me crazy! Finally I decided to take my vacuum to it, and it worked like a charm! Now I’ll sponge it down, flip it, and do the same thing on the other side.
