If I get the time and the money, I want to work on some ponies and I'll try making the molds using silicone and starch
has anyone done this molds?

Sadly I have no idea if it's been done before but sounds very interesting! Let us know how it goes if you decide to try it.

I mean, I have seen some mold actually done with it. You are supposed to pour cornstarch on a surface and add silicone on top, you gotta keep mixing and add cornstarch to get it like a clay or dough. I know it's rather flexible too.

I see there is instructions online to do this.
