Got a few more questions (sorry)...
I read on facebook about plasticard not being allowed because it melts in the mold-making.
So that means the molds you make are in metal?
Do you know of any other epoxy's or sculpting stuff that are allowed (or not), such as Instant Putty, Sculpy, Brown Stuff, Grey stuff, ... ?
Also, are there any limitations in size to keep it castable?
(e.g. if you would add a banner, how huge can it be? or if you give her wings, how wide can it max be?)
(Not that I plan to (try to) make a 25-components version that would need a dozen of molds in total though...).
