I've tried ballpoint, sharpies and pencils. The only thing that didn't smear when I put the finish on was the pencil but I have my doubts of it's permanence and it doesn't show up well on darker wood. I don't do enough to make it worthwhile buying a woodburner and with the cheap ones the tip is to far away to give me good control. Any ideas on something that won't smear when I apply finish?
