I bought a dozen eggs specifically for Dorothy and Abba to dye for Easter this evening. Dorothy wanted to try using natural dyes. She used onion skins (a mix of yellow and red onions) to make a brown color, beets to make red, red cabbage to make a surprisingly blue color, and turmeric to make yellow. They turned out quite well. Here you can see two of them, the turmeric and the onion skin dyes. She left the eggs in them overnight and when they came out, they looked amazing. When the dried they lost some of their intensity so she rubbed them with a very light coating of vegetable oil, which made them look remarkable again.
