Being a full time product and graphic designer, I spend all day staring at my computer. I love my job, but sometimes I just have to go get my hands dirty. I recently got together with a friend from fashion school on my parent's farm and we tried our hand at hand dying fabric with indigo. It felt amazing to work with real fabric again!
Most of what I know about working with natural dyes I learned at the Textile Arts Center (TAC) in Brooklyn. I enjoyed a weekend intensive with a few other women and learned about how to work with osage orange to create vibrant yellow, Cocineal to create fuscia and of course natural indigo for that ubiquitous denim blue.
If you're looking for some local inspiration, or maybe even a fabric dying class, I'd start with Indigo and Snow.
