Sewed from the top of the armhole to the bottom, across the body of the shirt and then angled back across the other armhole & up to the collar/upper arm. To be sure it doesn't slide on the hanger, I put a piece of elastic inside the back of the collar to put the hanger through. I even still have workable pockets if I can think of anything to use them for.

One of the things I like about it, is that I can unbutton the shirt to get to the bottom of the bag as I use up the pins.
