Have you seen the articles on Elizabeth Zimmermann's "Green Sweater?"
Last year, a lot of hubbub occurred over this sweater. It was an unknown design, knitted by EZ for her goddaughter, and worn for three generations. It was starting to wear (understandably), and the owner took it to someone to try to have it copied. Well, the owner wrote an article, "The Tale of the Green Sweater," about it (on Twist Collective), and the original was sent to Jared Flood of Brooklyn Tweed to photograph (pictures on Brooklyn Tweed, posted 9.15.2009), and there was so much buzz that School House Press (run by Meg Swansen, EZ's daughter) published a pattern. I've got mine!
The copy used Berocco's Ultra Alpaca, in a similar heathery green called Peat Mix, and School House Press has also had a run of the original wool, which is available, now, though perhaps not indefinitely. They also offer kits in both yarns. I've elected to use the Ultra Alpaca, but in a different colorway. It is called Blueberry Mix, mostly blue with purple heathering. Gorgeous!
The sweater uses steeks, again, so my current fumbling around with the Christmas Lights Cardigan will give me some good practice.
