Natural Dyes!
When I was studying for my masters it was so difficult to come across up to date articles on natural dyes. But since I've been back in the states working, in almost 2 years so many organizations and talk about natural dyes has sprung up around me. Check out this article in the New York Times about natural dyers around the USA.

Also, the Textile Art Center in Brooklyn has classes on growing natural dyes in a space in brooklyn as well as classes on dyeing your clothing with them.
As for my natural dyeing ambition? It's..coming along. Ha, not really. I've been collecting onion skins and am looking for places to buy organic cotton fabric. Hopefully I can take out time and go visit the fabric stores in NYC so I can get the ball rolling.
