ETA: It's been pointed out to me that a few aren't on the list (the biggest gap IMO being Wool of the Andes), and of course I failed to notice that because I already bought those a long time ago. D'oh. I hope they're just making more!
I caved and got some Shine Worsted for a baby sweater. Being home alone with a partially potty-trained kid, a nasty cold, and halfway through a pregnancy can lead to some impulse shopping to cheer one up... :-)
