I saw a thread about a tree decorated with eggs. I didn't want to hijack it, so I'll ask it here: Anyone else do things with blown eggs? Myself, I play with polymer clay. Some of them I completely cover, others I use the egg as an armature and dissolve it in vinegar. Here's some of my eggs.
(this is the same egg, just different views)
(this was made around a chicken egg, so those flowers are tiny!)
(this is the one I'm proudest of, I formed it around an ostrich egg, broke the clay off of it, and put it back together again so I could re-use the egg.)
