casting off with circular needles

[semajrn]

I am knitting a hat from the crown to the rim on circular needles, and want to know the technique for "binding off" while on circular needles. I cannot find any video demonstrating this method. Does anyone know of any links to a video, or easy to follow verbal directions?

There is no difference I've ever heard of between binding off on a circ and binding off on any other type of needle.
