The whole piece of silk
The Bundle; steaming
I dipped the leaves (fig leaves, and a plant I can't identify) into iron water for a couple of days, and left them there.
Wrapped them into a bundle of silk cloth; no mordant; an aluminium steamer. It's never cleaned in between dyepots, so has remnants of all sorts of plant dye in it.
I left it for a couple of days, after steaming it. Then unwrapped; and I think it's come out rather well! Am leaving it to settle for a bit; then I will iron it to fix it, which will flatten the fabric.
I'm rather happy with the results.
