Get out some jars or containers for your dyes- I like old mayonnaise or jam jars with screw on lids.
Put 2/4 cup of hot water and 2 tsp. of vinegar in each jar. Add your food colouring. You will need a total of about 25 drops.
Drop in your hard boiled eggs and let sit for 2-5 mins. Take our with spoon and let air dry.
Orange – mix about 10 drops of red with about 15 drops of yellow
Turquoise – mix about 5 drops green with about 20 drops of blue
Violet – mix about 12 drops red with about 12 drops blue
