(While this explains how to dye eggs, the same dyes can also be used for play silks)
Red-cabbage dye: 5 cups chopped cabbage (blue)
Turmeric dye: 4 tablespoons turmeric (yellow)
Onion-skin dye: 5 cups onion skins
Beet dye: 5 cups chopped beets (red)
Coffee dye: 1 quart strong black coffee
Paprika Dye: 4 Tablespoons
Really you can experiment with any plant materials but sometimes the results are not what you would expect.
1. Select a dyeing agent, and place it in a blender with a quart of water and 2 Tablespoons White Vinegar. Blend thoroughly. If you need more water then you should make sure to add more vinegar also.
Now this can be a bit of science experiment because you can dye the eggs one of two ways.
2. You can put the eggs in this solution in large dutch oven and boil them lower heat and simmer for 30 minutes. This will create a dark color.
3. You can also allow the dye to cool and soak eggs that you have already boiled in the cooled, strained solution. The color will not be as dark.
4. You can also play around with putting the eggs first in one color and then in another to try to create other colors.
