Gently place eggs in single layer in large saucepan. Add enough cold water to cover eggs by 1 inch. Cover. Bring just to boil on high heat. Remove from heat. Let stand 12 minutes. (Adjust time up or down by 3 minutes for each size larger or smaller).
Pour off hot water and rapidly cool eggs by running them under cold water (or place in ice water) until completely cooled.
Mix 1/2 cup boiling water, 1 teaspoon vinegar and 10 to 20 drops food color in a cup to achieve desired colors. Repeat for each color. Dip hard-cooked eggs in dye for about 5 minutes. Use a slotted spoon, wire egg holder or tongs to add and remove eggs from dye. Allow eggs to dry.
Two-toned eggs: Dip top half of hard-cooked egg in 1 color and the bottom half in another. Or, dip each half of the egg in the dye for different lengths of time, creating different shades of the same color.
Painted eggs: Mix 20 drops food color and 1/2 teaspoon vinegar in small container. Paint hard-cooked eggs with a small paintbrush or cotton swab. Go wild with stripes, polka dots and zigzags.
Designed eggs: Before dyeing, place rubber bands, stickers such as chicks, rabbits, flowers or other springtime favorites, or paper reinforcements on the eggs to create the design of choice. Once dry, remove the rubber bands, etc., to view the design.
Personalized eggs: Write initials, names or draw pictures on the egg with a white or light colored crayon before dyeing.
Marbleized eggs: Mix 1/4 cup boiling water, 1 teaspoon vinegar, 1/8 teaspoon oil and 4 to 8 drops food color in shallow bowl. Gently roll egg in the mixture for 30 seconds, or until the egg is the desired shade. Transfer the egg to a second color mixture, and repeat the process. Allow the egg to dry completely. Wipe away excess oil with a paper towel.
Color wash eggs: Place several eggs in a colander in the kitchen sink. Splash eggs with vinegar. Drop yellow food color onto eggs. Gently shake the colander for a few seconds to help the color spread. Let stand 30 seconds. Repeat with 1 or 2 additional food colors. After the final stand time, lightly rinse eggs with water. Drain completely. Allow eggs to dry.
Egg Dyeing Tips:
• Line work surface with layers of newspaper before dyeing eggs.
• Gather all equipment including small bowls or cups for each food color, spoons for each bowl and paper towels for spills. Bowls should be deep enough to completely submerge the egg.
• For easy clean-up, use soap and water repeatedly to remove food color from hands and most kitchen countertops. If needed, use all-purpose cleaner with bleach for countertops.
• Make an egg drying stand out of a paper towel tube cut into sections.
