You will need eggs, 4ts vinegar and color for egg dying (edible) or food coloring.
Wash, check and boil (hard) eggs as usual. Wait until eggs are room temperature.
Mix the color and vinegar in 1.5l lukewarm water in a bowl.
Easter eggs with leaf imprints, and for lines, wrap eggs with several rubber bands before dyeing them in colors. Its always a pleasant surprise how they come out. 🙂
