Watching Crank Yankers (which I must admit I enjoy) I wondered how they get these characters' weird shaped heads. It couldn't just be foam sheet could it? Then I saw the cover to the "Making of Muppets from Space" book and noticed a hand with a clipper/shaver thing on a block of foam, would this be a good technique to get some unique head shapings? Ya know, get a big block of foam, then shave away at it until I get the desired effect? Then cover in whatever fabric I have to represent skin? David.
