Turmeric is awesome. We had a good time. Following the directions in the book The Handbook of Natural Plant Dyes by Sasha Duerr, dying with turmeric (and no mordant) was fun, easy and dramatic. I used mostly small pieces, as I wanted to experiment with different fibers, and one larger piece, a home-sewn white caftan. (I made the caftan a long time ago from a 1-hour caftan pattern and it took more like 6 hours, as I recall!) None of the photos showing the dyed cloth have had any touching up or editing. One dye-mix transferred very well to two batches of cloth, after that it began to fade. I don't have pictures of the last attempt but it is much lighter.
I was going to give the exact directions here but decided I shouldn't, copyrights and all. But the book is awesome, too, in case you're wondering.
Turmeric ready to go.
Items left to right: Cotton bag, wool yarn, silk organza, cotton caftan, cotton print, piece of cotton t-shirt, and piece of cotton trim. The wool & silk took the color a little more than the cottons. All of these have been handwashed in cool, soapy water and rinsed until the water ran clear. I think I'll iron the caftan to help it hold the color, but I really don't know if it'll help. Everything I've read about turmeric says it loses its color and I'm hoping that's not the case, especially with the caftan!
This belt was handwoven with chenille yarn and various bobbles & beads & other yarns without a loom. It was begun on a long-ago Brigid's Day and took many moons to finish.
After all this, I started noticing turmeric all around the house . . . a wall in the
basement, the living room curtains, and there's more.
Synchronicities abound around turmeric!
