Depends on how stretchy you need it. If it's the cuff of socks, you'll probably want to do a special BO for that extra stretch. But for sweater edges, it should be fine. Check out the video in the BO section, I think I call it Basic Knit BO, alternating with Basic Purl BO. It shows the method briefly, and I demonstrate its stretchiness.
