Cut the nylon stocking into 5 inch squares.Stick a couple of leaves or flowers on each egg with a drop of water, then wrap it gently in the nylon stocking and tie it at each end.
Add the the onion skins (+ beets if using) and the vinegar to a big pot and cover with water. Bring to a boil and simmer for about 10 minutes.
Add the eggs to the boiling water one by one and boil for 8 to 10 minutes to your liking.
Allow to cool completely.At this point you can remove the eggs from the hot water or you may refrigerate them in the liquid overnight for a deeper color.
Once cool enough to handle transfer each egg to a plate and cut the stocking with a pair of scissors . Discard the herbs and pat them dry with a paper towel. For extra shine you may rub them with a little olive or coconut oil.
Notes
For the marbled eggs design, wrap each egg in a few yellow onion skins, then wrap tightly in a nylon stalking. Boil in yellow onion dye following the above instructions, only just using yellow onion skins.
