I finally have a perfectly cast puppet. It’s taken 3 weeks and 7 runs but all my puppets are now foamed up. It was an experience which seems unlikely to be repeated any time soon. So why did it work this time? WHO KNOWS! I have my theories but I may never know what really went wrong (or right as the case may be) I spoke with the people who manufacture the foam who helped me narrow down what could be the problem so a big thank you to Arnold Goldman at Monsters Lab. If nothing else this episode will change the way I prep my sculpts, molds and skeletons before running my next batch of foam. Of course … it may be three to four years before I run any new puppets so I really won’t need to worry about it until 2020.
