i was recently looking into making some costume stuff for myself and friends. i have never used foam or wonderflex before and have only read about them. i hear wonderflex you heat to get to maintain a shape and foam you just cut and bend then glue together with heavy duty type furniture glue or something. anyways i'm just curious if anyone out there who has experience with either one can tell me some basic things they've learned while using this stuff and where they buy it from? any help would be great, thank you so much everyone!
