If your template has straight sides like squares or rectangles, I go to Lowe’s and have them cut it for me out of their plexiglass. If it has curves, then I get my son to cut them out for me. It cost me about $1.50 to get a nice template that I use with my rotary cutter. I ask them to use their leftover plexiglass as my pieces are rarely larger than 10 x 10”.
