The gal who made one for my grand-daughter was an Avon lady, but she showed me how to make them. It's hard here because of the high humidity. The ' egg' is made of white sugar and egg white, in a form. After it sits a few days, you remove the mold, and gently hollow the inside sugar out. Then, using cake icing tips and wee ceramic or plastic critters, you can make them. But again, the humidity can melt them into yuk if you don't keep them in a warm dry place.
