Jen, who sometimes mentions me on her blog but always forgets to link,
recently blogged her finished 6th Sense sox and thanked me for showing my "no-measure" technique at the last
Sip, Sit & Knit. The technique is embarrassingly easy, and stems from my reluctance to actually measure anything; I always measure stuff against parts of my hand. You know, first knuckle = 1", index finger = 3", that kind of stuff. Anyway, for cuff-down socks, I measure against my whole hand. I explained it to Mary & Jen like so:
I slip the unfinished foot over my hand like a weird glove, and lay the narrowest part of the short-row heel over the tips of my fingers. I smooth the knitting down over my hand (but DON'T STRETCH) and when the working edge reaches the first "bracelet" crease on my wrist, I start decreasing for the toe. Assuming I'm going to decrease about half the necessary width every other row, then the remaining width every row, this always gives me a perfect length for the foot.
Mary & Jen received this information with wide-eyed, open-mouthed agogness, and then both immediately started bowing & chanting, "We're not worthy". Aw shucks, girls, come on. This is just me being lazy. [blush]
