Rosalind is a seamless sweater; the body is worked in the round to the armholes and then it is split for front and back, each of which is worked flat to the neckline.
The shoulders are joined using a three-needle cast-off.
Stitches are picked up around the armholes and the sleeve head shaped using short rows; the rest of the sleeves are worked in the round down to the cuffs.
