The couple left to be stitched at the bottom will have to be done after the edges are finished (the back covered). Since, as i mentioned before, that “symbol”/shape has shown up before often in my work, i can see these being a focus for awhile in other pieces.
I was quite shocked at how much colour washed out of the soda ash modified one–in the bath, they looked a warm reddish gold, but most of it disappeared. The best was just plain old alum with the dyebath, though i did get a surprise from an immersion of white cotton thread in the exhausted ammonia modified bath, peachy!
I’m wondering if there was a chemical reaction similar to madder, in that first the yellows are extracted (poured off in madder), and then the redder tones show up? I’ll test that a bit more, as i do like that shade. Other than that, i won’t bother with gathering this plant material again–yellow is basically yellow, after all, and there are a million plants that give that 🙂
