I knit and knit on. After dividing for the sleeves, I knit to the end of my skein, merely an inch or so more. Rather than starting the next skein, I decided to start the sleeves.
I have discovered when knitting top-down one piece sweaters at least in my size, it is easier to not wait until the end to work the sleeves. By the end the sweater is so bulky and heavy that I just find working the sleeves less of a pain when done earlier.
AI at any rate, I here present: half a sleeve.
