Do you think you might be able to get some nice movement in between two silk sheets? Spining would not be possible, of course, but maybe some little stuff... I don't know, just an idea. And I REALLY wish there was a way to increase the speed of "broiling down ideas"...
I'm not sure what you mean - the puppet is operated directly from behind, so the only way to insert it between two sheets is to work from below. And that's not how I want the puppet to be operated.
... In other news, I have found a local supplier (in the same state even!) of plastic sheets. I received the order yesterday, and they're very cheap (a few bucks per sheet, and they're like, 1m long X 50cm wide), thin but flexible, and come in a range of colours (white, black, opaque colours and transparents). I've been playing with a small cut off piece all day and am really happy with it. I'll be able to start making these new puppets very soon!
