Indeed, my little flag is still braving the elements! I made it out of card-stock paper and ran it through my ink-jet printer, programmed with a fold-over pattern. Then I stuck the two sides together with double-sided tape, attached it with transparent tape to a "flagpole" made out of a white metal coathanger and mounted it outside my bedroom window at about a 60-degree angle from the horizontal.
I live on a busy street, Southeast Powell Boulevard, so even though the flag is small a lot of passers-by see it. "It's cute!" (We live in a second-storey apartment, so if anyone wants to steal the flag they'll need a ladder.) With all this rain, the brave little flag is starting to run a bit; so I'll have to go get a "real" one at Elmer's Flag and Banner here in Portland. But the little paper flag has stood up nicely so far to all the rain, sun and wind!
