craftgrrl | bottle cap belt advise please!

So, late this evening (or maybe very early this morning actually)
a friend of mine let me know that friday, she gets married. For
a lack of a better word, I might say they're eloping. As part of
what they will be wearing, we need to make them customized
belts with bottle-caps (one with champagne caps, the other one
with caps from some 40's) How do we go about attaching these to
belts? Please keep in mind:
-Need to finish planning a sort of secret last minute wedding
-Do it all by friday
-Since nobody knows, there's no extra cash flows
(does the rhyming make the question more exciting?)
-have it done as quickly-and-cheaply-by-people-who've-never-done-it as possible
(ooh bad rhyming followed by bad grammar, this is sounding gu-hood)

so, yes, suggestions, anyone?

p.s. (by champagne "caps" I think she means the little metal taps that separate the corks from the wires that hold the corks in place.)

(to be cross-posted anywhere I can think of)
