I am confused doing short rows for a collar in rib stitch. Any hints?
Confused about what?
it is no different than doing short rows in any other pattern stitch.
I prefer the turn and YO method rather than the turn and wrap method.
See if this isn't a simpler and less confusing way of doing short rows.

With ribbing, just remember that you want to maintain the pattern, no matter whether a st is slipped or you turn and work back on your knitting. Good luck with it!
