for easter last year we dyed some chicken and duck eggs a gorgeous shade of blue, by using red cabbage! Yes red cabbage turned them that beautiful colour. We also tried turmeric, to make a yellow dye and to mix with the cabbage for a green but that didn't work, so well. We are going to try other natural dye's this year, onion skins and other veg! What have you used? do you have any recommendations?
