I saw the title of this thread and thought "How many ways can we come up with to use a Buff?" Here are a few more to add to the growing collection. Anybody willing to try out how well the Buff works as:
coffee filter?
powder puff?
filled with thick paint and used as a "blotter" gadget for painting with stencils?
tourniquet?
since it works for ice cubes, it should also work to hold a heat element for soothing sore muscles without burning your skin, right?
stretched over a frame to make a small box kite?
as a stretch bandage holding a couple of sticks in place around a broken leg or arm?
dropped hanky to test a gentleman's interest? (and which would work better for that, sweaty or clean?)
fly swatter (streeeeetch, and then snap!)?
emergency replacement bar tape?
group tour guide's follow-me flag?
fish trap?

OK. That's my dozen suggestions. Not all as good as the ice pack one. I'll definitely have a use for that come summer! Still, just as a challenge: How long can we make this list? And would the manufacturer reward us for it with buffs to match the new TE jerseys?
