match said:Tannins dye fast, as do lichen-based dyes, but then you need quite a lot of lichen, and I always for some reason feel worse about pulling up clumps of lichen than I do about stealing tree bark or plant leaves
Oh me too, I just refuse to use them at all for public demonstrations. Even some workshops I skim over them. Same with the fungal dyes, good though they are.They lichens take so long to grow round here.
