Hello everybody, I am no photographer, but I have question about background paper I hope you can explain to me. I work in the theatre and we wanna use for the set of the performance background paper, white 2x11. Performers wanna write on it with charcoal - is it possible? Is the material fireproof or not? I don't know the material at all, so I am supercurious. For instance this one: SBP01 Achtergrond Rol 2.00x11m arctic white thank all of you in advance!
