Next, grab a white egg straight out of the carton and cover the entire egg with pieces of onion skin so that no white spots are showing. This is a bit tricky - those little buggers can be slippery!
Now, grab your cotton string and begin wrapping around and around the egg. Make sure you leave a little tail at the beginning because you will need to tie that to the other end of string after you have wrapped all the way around.
Place all the wrapped eggs in a large pan.
Pour your onion skin water, with whatever onion skins are leftover, over your wrapped eggs.
Boil eggs for 20 minutes. This is important that you boil for 20 minutes. It makes the colors more vibrant!
After they have boiled for 20 minutes, cool them down in cold water. You can open them right away or you can do what we do and save them for Easter day and we all open a few. Its like unwrapping a gift because they are all different!
We usually place them back in the egg cartons and wrap in a plastic bag to keep moist. If they dry out too much the onion skins dry onto the egg and need to be soaked again.
Here is one I "opened". Pretty gorgeous huh!
