A small pile of unpainted, latex skinned, polyfoam Zombie Heads made for Moonshine of the Damned. I'm tying to get some of the FX prepped early for the series using what little materials I have lying around. In this case I ran out of polyfoam - didn't have that much to begin with, but what little I had went decently long way. This was about 1/4 of a $40 kit, maybe a 1/3 at best - so I should be able to get quite a few more from a new kit, especially since I now know the exact amount needed to fill the heads without wasting very much of the foam.
I'm looking into some new zombie prosthetics this week as well, I normally like to master mould them so I can reuse them for the shop later, but in this case I'll just be making them and setting them aside for now until I can master mould them down the road some time.
Still looking to raise money for the series as well, we're still hovering around the 1/4 mark - got a very long way to go yet. If you're interested in helping out, check out the page I've got set up: http://www.themonkeyrodeo.com/BZK3/
