Shibori is a Japanese dyeing technique that involves folding, twisting or bunching cloth and binding it.
Here I folded a wool blanket that shrunk and tied it with jute. Then soaked it with water.
Then I dipped the tied blanket in a pot of black walnut dye for a few minutes, turned the blanket and dipped the other side. I left each side in the dye pot for about 10. Untied the blanket and washed it in a mild detergent and put in the dryer.
