I've always wanted to try Indigo dyeing. I had the opportunity once in a Yashiko Wada workshop. She was in Asheville for an art related event and did a one day deal but covered many of her processes so our time with the Indigo pot was limited. I worked frantically to get some pieces done but never saw the actual process of how the pot was set up. I've done some reading and the real deal uses lye which does not appeal to me. Pro Chemical came out with pre-reduced Indigo - no lye is involved, only Thiox and soda ash - things I'm more comfortable with.
Kay who is a master at this would know the correct term for this type of Shibori.
