Short rows can be done for shoulder shaping as well as for increasing in the bust area, heels, and just shaping in general.
For how to do it for shoulders, reread the post where I suggested it. You would work across the back, stop a few stitches from the armhole edge, turn, work across, stop when you have the same number of stitches left on the other edge, turn, work until the same number of stitches from the previous turn (not the edge, where you turned before) and turn again. Repeat.
For a pattern that uses short row shaping, look up Calorimetry from Knitty. It’s a headband/half hat pattern that curves from the shaping.
