Emily suggests that the universe is conspiring against my knitting. While I do not think my knitting is that important to the universe, there is some support for her belief. For one thing, I am working next Saturday as well. So I called the LYS, thinking I might be able to arrange some quick transaction over my lunch break — and sure enough, they do not carry sport weight cream-colored wool, either. So there is a serious dearth of the one yarn I need.
For another, the pattern for the London Beanie has unaccountably disappeared from the site which feebeeglee so kindly linked me to. So here I am, ready to do the decreasing, and the directions are gone. I can just do it mathematically, of course, but I do not know whether the London Beanie has some special thing about its decreasing. And I suppose I will never know.
