Tempest II uses Dream in Color "Baby" (their lace weight yarn), in "November Muse" (brown) and "Lipstick Lava" (Melon) from The Loopy Ewe. I've just finished the back. I had to use one size larger needle (7) than the Great Adirondack Silky Sock version. The Dream in Color is a subtle variation in color instead of being truly variegated. It is same yarn dyer as the Central Park Hoodie I made, except that was the worsted weight (in "Ruby River").
