So you want to start off with a hollowed out egg. If you never have blown out an egg before it is easy. Just take a needle and poke it on one end then poke a larger hold on the other end. Then blown in the smaller hole really hard and the yoke should come out. You can make a paper egg and it will work too (I'll put up how to do that later). Once you have your egg and it is dry, then you cut think slices from your can and gently press onto the egg. If you press to hard your egg might break....this happened to me on my purple one. =( *sniffles*
Then bake according to your clay's directions. I like to sand and then glaze to make it all nice and shiny, but I still have to do that part. Then you can add some string and hang them!
