Can you help me build a May pole?

I'm trying to organize a May Day event for my college campus. I'm using a 12-foot-long carpet tube anchored in a 5-gallon bucket of cement for my pole. Does anyone have any advice as to what kind of ribbons to use (satin? grosgrain? something else?) and how to attach them to the pole? I was thinking of either staple-gunning them on, or cutting holes in the top of the pole and threading the ribbons through, so that each ribbon is being pulled by two people (one on each end) rather than one. If anyone has experience with this sort of thing, or better ideas, I would love to hear them. :)
