I found this really great video about hand beading from a costume shop in New York that made the costumes for Wicked, and I actually think I visited and toured this costume shop when I went to New York with my sewing class.... but I can't remember exactly. It LOOKS like the shop. The tables and windows look familiar. And I'm pretty sure they said in the tour that they did the costumes for Wicked when I was there. I also used their bathroom, which was really nice. I also had eyelids the size of strawberries due to a severe sinus infection that whole week. But discussing the Wicked costumes is what I really remember.
