The HAPPEN cardigan is the sister of the HAPPEN sweater. And it combines the best of both, cardigan and sweater (well, to my mind, as I mostly wear it with the 2 top buttons unbuttoned :)

Any pattern questions are welcome here

HAPPEN cardigan is worked seamlessly from the top down.
 You start working the upper back until the length of the armhole. Then you work the fronts (double button band included) to the same length. Join back and fronts to work the body down to the bottom ribbing. Pick up the sleeve stitches from the arm opening to work the sleeves top down in the round.
