Cut open neckties at the inside seam. Remove all lining and discard. Iron open the tie from the wrong (inside) of the fabric.
Cut out squares of silk fabric and muslin enough to fully cover the egg and be able to be tie closed on top. NOTE: My squares were between 5-6” and were by no means ‘perfect’. I eye-balled the size needed.
Place a square of muslin onto a counter top or table. Lay on top of that a square of silk with the right said facing up. On the right side of the silk square place one raw egg. Carefully wrap the egg in the silk, trying to keep the silk as smooth to the egg as possible, and then muslin, tying the top snugly closed with a length of cotton string.
Select an enamel or glass pot tall enough to allow eggs to be covered with liquid as well as large enough in diameter that the eggs will rest close to each other but not be smashed in.
Place the eggs in the pan and add 50% white vinegar and 50% warm water enough to cover the eggs but not much more so the eggs do not float.
Boil the eggs gently for 45 minutes with the pot partially covered. In a second sauce pan warm an additional amount 50% white vinegar/50% water to replenish the egg pot if evaporation reduces the water volume during boiling (just add it to the egg pot if needed).
While the eggs are boiling, line a large baking pan with an old towel or several layers of paper towels. Also ensure the tongs, scissors and egg carton are nearby
Once the eggs have completed boiling, remove each one by one with the tongs and place in the towel-lined baking dish to cool fully. When cooled, cut the string with the scissors, carefully peel off the muslin and silk. Allow the egg to dry fully in the egg carton, being careful not to smear the transferred dye when the egg is still wet. Discard the used silk and string; the muslin can be reused for another dying.
Once cooled you can rub the egg gently with cooking oil for a bit of a shine or leave it as is. Refrigerate until using them for egg hunting. Note: some of my eggs emerged with slight indentations though were still fine for egg hunting. As a precaution the dyed eggs should be used for decorative purposes only (do not eat them).
