while doing the work, Alyssia accidentally pulled a very young coyote bush. I brought it up and cut it, pieces of branches, stem and leaves. In a pot, boiled moments then outside into the copper pot with that Iron Something, a horseshoe from the road, bundled cotton, silk noile and linen. I googled. Does coyote bush have tannin and got a great dye page. Yes. Coyote Bush DOES have a lot of tannin. Tannin. mordant. just overnight and through early morning....the green of this Hill. Green.
