You may want to consider making a bulletin board of symbols during Lent and ask members of the church to contribute the symbols they make. If the activity is part of a church night event, plan alternative activities for younger children because of the hazardous materials used in making these eggs. True Ukrainian egg dyes are toxic. Lighted candles are also used in the process. Use a well-ventilated room for the work and provide several eggs per person.
Raw eggs break easily, and it often takes two or three tries before success.
Make sure you have a booklet that explains the symbols used, if you want to be authentic. Each packet of dye will color approximately 12 to 18 eggs before losing its strength. Once mixed, dyes can be stored in glass jars with tight-fitting lids. Once decorated and cured, Ukrainian eggs will last indefinitely. Let children cut out a large fish outline on colored paper and then write a prayer on the fish.
