Repeat, painting the eggs with various shades in various places. Use your imagination. Overlap some colors for special effects, or keep it monochrome. Set the egg aside to dry when you're finished painting.
The more patient you are and the more the egg dries, the better. When you un-wrap the egg, you'll be left with a design that resembles armadillo skin. You can use this technique on plain white eggs, over a base coat of color, or even over marble colored eggs.
Another technique which will give a subtle textured effect to a solid colored egg is to wrap the egg in cheesecloth, as per the instructions above, then dip the whole thing in the cup of egg dye. Let it sit until done to desired shade. Let dry (it doesn't have to be bone dry, but the drier the better) before carefully removing the cheesecloth.
