Thanks Barry this does help. I figured the thicker would hide the see through. Then I thought I could cut the single lines wider but that will leave some very thin pieces left. I did try the spiral 3 and 5. They left a lot of fuzzes, the control was pretty good but I liked the straight blade best. It cut with almost no fuzzes. If anyone has more information on this feel free. Is it possible for the kind of wood, and thickness be posted with portraits, puzzles, and other projects? Thanks Rich
