My tattoos make local eggs even more local :) Get them at http://www.etsy.com/shop/sflocal or www.sflocal.net now for Easter!
If you have no patience: stick tattoo to the raw eggs. (Surprise your roommate when they open the fridge)
If you have some patience: stick tattoo to the hard boiled eggs. (Wow your coworkers at the lunch break)
If you have A LOT of patience: use a needle to poke two holes on opposite end of the eggshell. Blow the egg white and yolk out. Clean the eggs. Let dry. Then stick the tattoos on. (Permanent display and great gift!)
Larger, white eggs recommended.
