Using Barbara Walker's - Knitting from the Top as a guide I :
- decided on stockingnette and round neck pattern
- multipled gauge with 15" back-shoulder width
- cast on using provisional method and knitted back piece
- left 1/3 sts on work yarn for neck and worked left, right front
- shoulders worked with short-rows
- when front and back equals 1/3 of armhole, turn and pick-up sts for sleeves (see arrows)
- increase both sides at front then join collar to work in the round down body
But.....there are totally horrible kinks at sleeve pick-up points (arrows on pic) caused by the abrupt turning and I do not think they'd be smoothened out with blocking.
Have decided to frog when I get home tonight, maybe forgo the set-in sleeves but go for the 'body-first' method of knitting straight down first where sleeves are picked up later and working in shortrows from the cap.
More updates on the technique if I don't decide to frog everything and go back to good ole' knitting from the bottom!!!
