I ended up going with this simple sharpie setup. No offset or programming to make lines match up if you want to do multi layer or mixing materials. The only down side is removing torch and hanging it out of the way. I have velcro strap on hanging pole. I might make something in plastic but just haven’t yet. Not saying it’s be is better than other but for me something simple and easy was right choice. I’m not personal friends with David that sells this sharpie but I use mine almost every weekend and love it.
