Erm, I don't know if this is an okay place to ask this, though there were a few threads on creating toys from scratch and whatnot so I figured I'd ask. If it's a bad place for it, advice on where to ask would be helpful.
Basically, I'm looking for something I can mix together, pour into a custom mold and hand roto-cast to create a hollow figure head, about 3 mm thick and is slightly firm but flexible enough that when I take a needle and sew hair into it, it won't crack. Like a Barbie head.
I recieved sample of Alumilite FLEX but they were sticky
. Smooth-Cast 45 seemed like a good bet but when I cut a 3mm piece, the needle created tears that cracked when it was flexed.
The resulting pieces have to be paintable with regular acrylics (no silicone), I have to be able to get it sent to Canada and it has to be available in normal hobbiest quantities.
