I've seen somewhere, but I'm not sure where, that some one used a pliable medium to make their own molds. She took a kelly doll (barbies little baby sister) and pushed it into this soft dough and it made a mold (when dried) of this doll. Does any one have any ides?//

Is this what you were looking for?

To make a mold that can be used over and over...use silicon plastique.

Silicone plastique is a great tool. Heres a link to a supplier.
