Did you know you can make simple Easter eggs dyes from ordinary food items? It's one of my favorite methods and as a bonus, they're all natural too! You can read all the details about these Natural Easter Egg Dyes on my blog, where I have a handy printable pdf with the instructions too.
This always feels like a bit of a science experiment to me too as some of the finished colors aren't what you first expect. For instance the red cabbage makes a very purple looking dye, but results in a lovely blue egg.
The basic process has two steps. First the food stuff is boiled with water and vinegar, and then left to simmer for a while to more deeply color the water. I then strain the liquid off into a bowl and let it cool. For the second step, I hard boil the eggs in the dye water I made, let them absorb the color, and watch them turn into beautiful Easter eggs. (One exception is the yellow dye water which can be made by just adding turmeric to the water)
For a couple of the dyes, you need to let the eggs continue to soak for a few more hours, but if you're patient you'll be rewarded!
It still kind of amazes me that onion skins, red cabbage, blueberries, and turmeric can make this pretty rainbow of colors.
