This is a pattern for a sweater worked flat and in the round, from the top down and with set-in sleeves.
The back neck is provisionally CO and the shoulders are shaped using short rows. Each front is worked separately, beginning from the shoulder sts of the back. After the fronts are joined, the monster motif is worked by intarsia. After the monster is worked, the front and back are joined and finished to the bottom edge, in the round. (side seams are joined with mattress st)
Sleeve sts are then picked up and a number of short rows are worked, until past the shoulder cap. The sleeves are then worked in the round.
Finally, the collar is worked by picking up sts around the neck and working a rib.
Block you sweater and go prowl…grrrr!
