Half Pint Farm handpainted wool in a stormy colorway. If you've never seen Ellen's colors, run, don't walk, to her site and get some. They're fantastic, and all of her stuff is next-to-the-skin soft as butter.
Decadent Fibers' worsted wool. There's about 500 yds here, and I see a glorious pair of very tall socks in this skein's future.
