I have always rest the stylus on the protractors that I have used, MintLP and
Dr. Feickert. Neither of these is made of paper though.
I suppose that short of getting a real protractor, you could try taping some thin plastic over the paper drawing.
I wouldn't do that, but it's your cartridge, you can risk it if you see fit.
