TeaKEY, I could never live up to that! :) I just post the steps because they are always interesting to me when others do them. The best things about the Creating forum are seeing the process, then the results. Everybody does things a bit differently, that's the fun part. Thanks, though!

Palama sent me some tips and some great links on mold making:

Here's the polytek site and another site for moldmaking (more along the miniature line, but some good info)...

More helpful step by steps at the Polytek site. They also have a video available, but it's $38.00. I spoke with one of the techs over there and he gave me a bit more insight. He said 3 coats of the polyurethane is best (around 1/4" thickness) because the thicker you go the stiffer the mold gets and thus more wear and tear. So more is not necessarily better. Also, it is good to shellac the inside of the mother mold so that it does not soak up the oils from the inner mold and cut down on the life of the mold. The product pricing was marginally better at the Polytech site and they have "trial pricing" on the first order. He suggested that I use plaster and burlap for the mother mold to cut down on cost. I'm still kicking that around because it's less durable than the specialized mold plaster.

Thank you Palama!

CONCRETE??

I have no idea of what mix or type of concrete to use for molding. Any suggestions out there?
