I'm trying to figure out how to knit set-in sleeves. I've already done the fronts and back of a cardigan, so I've got the armscyes all done. Now I just have to figure out how to shape the sleeve caps to fit.
I read through Knitty's series of articles on sleeves. I went over a bunch of different published patterns in the gauge I'm knitting at, to see how they do sleeves.
So I worked out the math for the first try at a sleeve last night while watching Eurovision. Hoo-boy. It's not the math. I can do math. The difficulty lay in making my brain concentrate on something intently for a longer period of time. All these months of not working means that I've gotten used to not having to think hard if I don't want to. It's terrible. I'm no longer adept at ignoring other things and paying complete attention to just one task. I better find a job soon. Luckily, most of the Eurovision contestants were so stomach-churningly horrible that my brain welcomed the opportunity to ignore it.
