First, blow out the eggs. Then make a pinboard for drying them: Stick flathead pins into foam board, forming a grid of pins that you can rest the eggs on. Dye the eggs as desired and let them dry on the pinboard, then spray them with an enamel finish (such as Martha Stewart Crafts sprayable gloss enamel; $7, michaels.com) in a well-ventilated area. Let them dry on the pinboard for 10 minutes, then repeat spraying. You can try this process on a variety of eggs, as we did here. The eggs’ natural patterns and hues produce different effects when they’re dyed—plus, the range of sizes will add interest to your holiday display. Look for a range of colors and sizes at local farm stands and specialty-food stores.
