Right, most people think mage and see the old guy in a purple star robe. I'm working on some more detailed costuming for my Mage: the Ascension live action character, and figured that this is really the only good solid place I could post and get some responses, so here goes:
I can provide more detailed information for those who would like it, but I don't think it's horribly important for this - the main reason is the fact I can find one company that supplies "Sintra." That would be Alcan Composites, and from the look of their website it's not a simple as ordering a sheet or two off their website (if such a place where I can order online is available, a link to such would be much appreciated).
As such I'm wondering if there are any suitable replacements to such a material. The closest I could find is a corrigated plastic sheet, and I'm not sure how that would stand up to a heat gun.
