Prepare your egg dye according to package directions.
Place your hard boiled egg in a piece of material. Secure the fabric, as tightly as you can against the egg, at the top with a rubber band.
Place the egg in dye for at least 30 seconds or according to package directions.
Remove egg from dye, place on paper towels and pat the outside dry with paper towels.
Let it rest for about 2 minutes then gently cut the fabric away from the egg.
Immediately pat dry again and let it rest for another 3 minutes to dry completely.
