Golden Blunder,

I use a product called See-Temp for my patterns. It is a transparent plastic or mylar material that has a flat finish. After drawing the pattern on plans it is very easy to trace it onto the See-Temp, I just draw the overlap by hand then using a #11 knife I just score on the lines and the template just snaps out on the scribed line. I them use the template to cut the film (I use MonoKote but this method will work on any film and on open or sheeted frame.
