 The Terracotta-eggs are first coated with two layers Napkin varnish painted. Let it dry. Then dilute Handicraft paint ..with water, apply splotches to the eggs and spread it by blowing 
Once the whole egg is covered with spots of paint and the paint is completely dry, rinse it with water - this will give you great and unique effects 
 If you want to completely cover the eggs with glitter, wear Napkin varnish and sprinkle glitter in. Repeat this procedure a second time.
