So I'm thinking about dying this shawl as I knit it, and this is making me think hard about how I'm going to accomplish what I want. Peacock feathers in reality look very little like the picture in my head, though I think most people would get my stylized mind version (I"m borrowing others images, so to give credit where it is due, these come from http://www.tonyhill.net/, http://community.livejournal.com/chicks_with_ink/59453.html; http://www.foxriverbnb.com/tribal.htm). I think the hardest part will be the iridescent green/gold/purple. But I think I can get what I'm after by applying those colors to vinegar soaked yarn and letting them work together. Or, I could end up with something the color of baby poo. What an adventure.
