I used to make those cut eggs and also psyanky-Ukranian batik painted eggss. I had art showings of my metalworks in the late 80's and wanted something to dress the gallery up with as a theme,so I did a lot of eggs. Some of my sculptures had enameled metal,so I wanted to do something like "Budget Faberge Eggs". There were actually places around Philadelphia-were I was at the time-that sold kitsky (styluses) and materials for egg art. I had cats at the time,so I stored them in locked cabinets or gave them away to friends.
I really liked holding the egg over a candle and melting the beeswax off when it was done,it smelled really good.
I was at a store buying eggs and a man yelled at me,"Just buy them! What are you gonna do, take them home and admire them or are you going to be like a normal person and eat them.?!!!" LOL
