I was looking at Glennis's blog, and that led me to her Flickr set, and THAT led me to search for indigo things on Flickr, and well, that always ends up with me wanting to show you the gorgeous things I found.
Glennis (Shibori Girl) taught a wonderful online class on shibori techniques. We used tiny vials of intense, easy to use Colorhue dyes, and smallish pieces of fabric in yogurt tubs. (I posted some of my results here, and here.) I had fun experimenting with silk. Using it for dyeing helped remove some of the mystique from the fiber, at least enough that I've been using it extensively in the Ancient Equines pieces!
