I have started messing around with marionettes but have been having a few snags on the heads. my personal predicament is that I have found that epoxysculpt is good for making heads and hands because it is strong and easy to sculpt with but very expensive. now I have heard rumours of an epoxy you get in a big block about a foot long that you slice bits off and sculpt with but when I looked on the internet web there was no trace of such a wonder existing. anyone who knows where I can find it or if it even exists?
