Ok, I know this has been brought up before, but being rather fluttery of mind, I am a bit confused with all the technical definitions and descriptions... Exactly what is the name of the foam that everyone is using for puppets? Is it this Neopro-something that I've heard of, or is it something else? Can it be bought in blocks, and is that how most of you professional builders get it? Or is it used in the sheet form? And were can you get it? All the foam seller's sites talk about 'closed-cell' foam and other junk and have all these measurements that I don't really understand (being utterly and wholy incompetent when it comes to learning my numbers ) Where would be the best place to buy this mysterious foam? I'm sure 'The Foam Book' covers this stuff, but, regretably, a foam book I do not have. - $$$ = ----Nate Oh, speaking of the Foam Book, would anyone happen to have a used copy of it just, say, laying around? I'd be very willing to take it off the hands of anyone who does for a 'used book'-ish price...just cant fork up enough dough to get a new one.
