A perk of working in a lab (and being in charge of ordering surgical gloves) is that I know, when plotting to make fingerless gloves for my lab mates, that S. has slim hands, but fairly long fingers, and V. has hands pretty close to my size. It's nice not to have to rely on guesswork when putting in the time to hand knit something. All I have to worry about is picking colours (royal blue for S. and pinky red for V.)
We all spend a lot of time in an overly air-conditioned computer lab, looking at highly magnified photographs of nerve fibers, and using software to analyze those nerve fibers in excruciating detail. Last winter we all had very cold stiff hands. I can't make myself a pair of fingerless gloves to wear while my compadres suffer with stiff chilly hands.
