Nestle each of your marbleized eggs in its own bed of grass. Using cardboard dividers, create 12 compartments in a shallow box or an empty shirt carton, then fashion a snug nest of dried grass inside each square. Save the lid for storage.
Tool & Material:
•Egg blower, Aunt Marge's 2-hole Egg Blower, surmastore.com
•Several mixing bowls, shallow and deep
•Liquid measuring cup
•Food coloring, including liquid brown food color, lorannoils.com
•Spoon and fork
With an egg blower, pierce the top and bottom of each egg, puncturing the yolk; carefully expel the contents. Rinse, and let dry.
In a small mixing bowl, combine 3 cups warm water, 2 tablespoons vinegar, and a few drops of food coloring. Place egg in dye, and leave it submerged until it turns the desired shade.
In a wide, shallow bowl, prepare a second batch of dye -- which will provide the swirls -- in a darker shade or a different color. Liquid should be 1/2 inch deep. Add 1 tablespoon olive oil. Run a fork through this mixture, creating curlicues of oil on the surface.
As oil swirls, place dyed egg in mixture, and roll it once around the bowl to pick up oil streaks; remove the egg.
Gently pat egg with a paper towel.
Let it dry. You can experiment with color combinations: Vary the base tints and the swirls to achieve striking contrasts, subtle shadings, or multihued richness
