[Hildegard_von_Knittin]

I've never heard "Bind On" myself,.... but cast off and bind off are the same thing.

If the rest of the cuff is in ribbing, just remember to bind/cast off *in pattern*... that means, if the next stitch is a knit stitch, knit it, then bind it off, but if the next stitch is a purl, you have to purl it, then bind it off. I think it;s more important for the bind off to match the pattern, than the cast-on, personally.
