These are great. I remember decorating some eggs when I was younger. I would drill out a tiny hole to get the yolk out (forgot how I did it) so that I could keep them without worrying about the eggs becoming old and smelling bad. My favorites here are the two blue eggs in the front. ^^
The decoration of easter eggs is a long tradition in our region. The eggs in the foreground were dyed and then with a sharp knife was scratched out the ornaments. The left and right eggs in the background were made in the wax batik technique.
