I’m not sure what kind of wood this is made of. I’ve sanded and degreased it but I’m still getting oily spots. The Micron pens definitely won’t work on this. They smear too easy even on paper. The sharpies are drying O.K. but the tips are wearing too fast. At least they’re cheap. It took the entire day to get this far. I didn’t want to start applying the ink so soon but I was losing my pencil lines. Even pencil doesn’t stick too this wood. I have a big smudge mess going on in the center, I hope that cleans up. I’ll let it dry over night and see what happens t’mar.
