After reading about creating an ice bath for dyeing with fresh Japanese Indigo leaves, I decided to try it, rather than create a traditional indigo vat. First, I pulverized the freshly picked indigo leaves, along with a little water in the blender, then scraped the mash into a copper bowl. This bowl was set in a larger bowl filled with ice, to keep the whole concoction cold. Next I entered a blend of wool and alpaca fleece into this mush and squished it around until the fiber was completely submerged in the indigo mash. Then left it overnight. That was it! So simple.
The next morning I rinsed the fiber and laid it out to dry.
It was a beautiful pale robin's egg blue.
After spinning the fiber, I knitted it up into a lace cowl
which I gifted to a friend.
