I've worked with Polymer clay, PMC, earth clay, plaster, carbon fiber and even latex (don't ask lol), but I wanted to know more about working with PVC Vinyl and creating molds for using it. I'm trying to make some new creations and possibly branching off to making cool kids toys locally (I know the kids I work with for storytelling at the hospital would love some unique one of a kid toys) but have never worked with this medium before.

Does anyone have any experience with PVC Vinyl or could direct me to some good sources? Suppliers aren't a problem it's going about the whole process thats catching me up. Thanks!
