The first remains of decorated egg were found in the Carpathian basin, in Hungary in an Avar grave, which is about 1500 years old. The pattern was etched on the coloured egg. This is the oldest form of decorating eggs. When you have dyed the eggs, take a tapering knife and etch the pattern on the surface of the eggshell.
