Folded Collar Bind-Off 

This tutorial shows you how to knit a Folded Collar Bind-Off using both a stretchy and a rigid method. This is a great way to work a folded collar for sweaters, especially cable-knits!
The stretchy bind-off is perfect for sweaters with snug neck holes that you still want to pull over your head comfortably, and the rigid method is a great choice for wider necklines, already large enough to fit over your head, where you might want to maintain a more inflexible neckline.
