Who knew that silk fabric transfers onto eggshells as easily as the dye in a decorating kit? Regular old vinegar plus hot water does the trick.
Step 1: For each egg, cut out a 5-inch square of patterned 100 percent silk. (We limited ourselves to black-and-white prints to achieve the effect above; colored patterns yield more vibrant results.) Lightly dampen the fabric, then lay it flat, right side up, and place your egg in the center. Gather the fabric tightly around the egg, like a beggar's purse, and secure with a rubber band. Repeat this step for the same egg, using a same-size square of plain white cotton and a second rubber band. Note: Use blown eggs if you'd like to keep your handiwork longer.
Step 2: Place eggs in a single layer in a nonreactive pot and add enough water to cover them by 2 inches. Add 4 tablespoons of white vinegar. Bring the water to a boil, then reduce heat and simmer for 40 minutes.
Step 3: Remove eggs with tongs and cool about 20 minutes. Then unwrap the fabrics to reveal the exquisite designs.
