Simple ribbed neckline (not folded) with tubular cast on.

Adding 4 extra rounds of short rows to the back.

Dividing for sleeves at the middle of the second flower repeat. Adding 2 sts for each sleeve.

Error for size M at the beginning of the first diagram: 1st increase round should read: Increase after every 10th st (rather than after every 21 st).

Only dicovered too late that it is not sufficient to follow just the diagrams - one must read the written instructions on the side as well to make increases and decreases at the right times;)

Shortening the body.
