Natural dyeing techniques

I've been experimenting with natural dyes and wanted to share some of what I've learned. It's easier than you might think!

Some dye sources I've had success with:
- Avocado pits and skins (beautiful pink!)
- Black walnut hulls (deep brown)
- Onion skins (golden yellow)
- Indigo (blue, obviously, but requires more process)

Would anyone be interested in a dye day? We could gather materials and experiment together.
