Any pattern questions are welcome here

This sweater somehow made itself and happened when I just want to try out some new (to me) techniques …

HAPPEN is worked seamlessly from the top down. You start working the back until the length of the armhole. Then you work the front until the length of the armhole. Join back and front to work the body in the round down to the bottom ribbing. Pick up the sleeve sts to work the sleeves in the round.
