Leave the eggs at room temperature for at least 2 hours. Put a towel or cheesecloth at the bottom of a large pot. Arrange the eggs on top, pour in cold water 2 finger widths above the eggs and add a spoon of salt. Leave them to boil for 10 min. after boiling point.
Dissolve the dyes in bowls or jars, as directed on the packets. Use thin candles to draw various symbols, signs, dots, suns, write names or whatever you like on the boiled eggs.
Put the eggs in the dyes and take them out onto cardboard after 5 min.
