I slightly change the construction I had used several times before. Started from the middle of the back with a provisional cast on. Knitted sideways in both directions. Then made some decreases after the collar. See more here. For future: to make it longer; to choose another pattern for collar. Not that “horisontal ribbing”, as I call it, is not nice enough but it stretches somewhat. Or to compensate it with some short rows. Used almost 2 skeins of the yarn. The yarn is really nice. Blogged here.
