Prepared Icelandic wool.
I was very excited for this class because when I first started knitting I watched the Elizabeth Zimmermann videos over and over and she seemed to use Icelandic wool for everything! So now I was finally able to meet some face to face. I really liked it. Alas, I had a really nice picture of the raw fleece and some samples that I had spun up and I lost it in cyberspace. :(
