Thank you!! It's made of real leaves. I gathered them and used them while they were still flexible. I glued them to the paper-mache mask form with superglue and then painted them with a glossy medium so that they wouldn't be so brittle.
No kidding, you have to preserve it! Hmm...there must be something out there that you can coat on. I know I've seen something like that before, but go figure I can't remember what it was called. I bet if you went to an art store and explained they could come up with something!
