Symbols of rebirth in many cultures, eggs serve as the perfect centerpiece for this festive wreath. To hollow out the eggs, working over a bowl, pierce one end of a raw egg with a pin. Pierce the other end, and use the pin to enlarge the hole slightly and break the yolk. Blow out the insides using an egg-blowing tool or rubber ear syringe, forcing contents of the egg out through the larger hole into a bowl. Do not let the liquid touch the shell.
