I would like to make a B.P.R.D. jacket like in the Hellboy comic but I'm having trouble finding something that I can modify. It seems that Hellboy wears a long duster but other BPRD members (Liz, Abe & Roger) have a short jacket version of it. It's hard to tell from Mike Mignola's highly stylized artwork but they seem to be made out canvas or denim rather than leather. Any guesses?
