I think Olfa makes a small cutting tool with two blades for cutting stencils. I think a soldering iron would warp or melt plastic. If you are going to use it over and over, I might use an exacto knife and cut the channels by hand. I have a set of pen like knives that I got at the $ store one time, they are handy for lots of little jobs.[ATTACH=CONFIG]545545[/ATTACH]
