Natural dyes

WOAD! I wanted to experiment with the smelly bucket of woad, but I didn't out of consideration for other's sense of smell. Ive always been curious about woad and its use by the Picts, and I want to learn more about it. I knew that woad was used to dye the skin and was used in actual tattoos, but I was unaware that it could be used on fabric. I also was under the impression that the plant used in the dye had become extinct...but the bucket of pigment and urine proved me wrong. I was also interested in indigo, my theme here seems to be blue.....at some point I hope to dye my comforter blue, but I think I need to consult more with Jody and read more before I try anything
