Here at GG, we're going to try some new-to-us natural dyes. We do use beets & onion skins but Two Men and a Little Farm have inspired us with their terrific chart of multiple possibilities. (TheKitchn also has a good post with concise instructions & photographs.)
It's always fun to hop over to Martha Stewart's site; no one else has such a round-up for holidays & Easter is no exception, including last-minute ideas.
