This step can be done a day or two ahead of time.Fill a medium stock pot with 3 quarts of water. Add the vinegar and stir.Add the onion skins and push them down into the water. The stockpot should be about two-thirds full.Over medium heat, bring the onion skin mixture to a boil. Reduce heat to low and simmer for 20 minutes.Remove from heat and allow dye to cool.
Add a Leaf Design
This step is optional. If you just want red eggs, you can skip this.Use scissors to cut the legs of the nylons into 4-5” tubes. Tie a tight knot at the end of each tube.Use a little water to adhere a small leaf or flower to an egg.Carefully insert the egg into the nylon tube and draw the nylon tightly up and around it. Secure the end of the tube with a twist tie, yarn, or twine.
Dye the Eggs
Put raw eggs into the cool dye. Make sure they are completely submerged.Bring dye to a gentle boil, then turn off the heat and allow the eggs bathe in the dye for 20 minutes, or until they reach the lovely brick-red color you want.Remove eggs from dye bath and allow them to cool completely.
Polish the Eggs
Remove the nylon tube from each egg. (You can use these again.) Carefully peel off leaves or flowers.Polish eggs with a little olive oil and a paper towel.
Notes
We recommend leaving the onion skins in the dye while the eggs are boiling, using the skins to separate and cushion the eggs as they boil.
