I used to buy Mylar heat resistant plastic sheets. they were not clear but still could see through to trace template outlines. i am not near anything now and usually buy online. got a pkg of clear plastic. Traced outline and cut but the permanent marker had to be wiped off of the plastic. i used to write on the mylar one.
where can i find good mylar plastic? one review buyer was disappointed. no longer can see through the plastic so cannot trace.
