I like the rubber cement idea– it works. I have ironed my pattern pieces onto the freezer paper you’ll find at the grocery store. The plastic in the paper preserves the pattern pieces a bit longer than if they were straight paper.
I’ve also drawn the pattern pieces directly onto the paper and then ironed the pieces onto the glass. The plastic melts onto the glass and sticks through a few slogs through the bandsaw or Taurus.
The rubber cement does the same thing and is cheaper– it “waterproofs” the pieces a bit as you make the way through the sawing.
