I got really inspired by these beautiful blue Easter eggs I came across on Pinterest and decided to do something similar myself.
I used one bowl with around one and a half cups of boiling water and two teaspoons of white vinegar. First I added two drops of food colour to the bowl and dipped my first egg for a few minutes. Then I added five more drops for my second egg, another five drops for the third egg, another ten drops for the fourth egg, another 20 drops for the fifth egg, and another 20 drops for the sixth and last egg. You could also set up six bowls in different shades of blue and then dye six eggs at once.
I let the dyed eggs dry off on paper towels before placing them back in an empty egg carton.
Since I was dyeing eggs to use as votives, I had already emptied and rinsed them out, but you could dye hard-boiled eggs or eggs that you have blown out.
