We all get in ruts fixing things; we all have our favored solutions. Not surprisingly, I tend to grab a chunk of wire. Since I'm also often on a faire site and we're pretty used to improvisation, I end up wire-wrapping some things that I'm pretty sure shouldn't be wire-wrapped but hey, if it holds up your tent/gets you home, who can argue?
Sometimes I get asked what the weirdest thing is that I've taken wire to. It's awfully hard to pick just one, so instead, here is a list:
--Teeth. Oddly enough, never a shark's tooth, but I have wired bear, boar, and coyote teeth. Not really hard to do although unfortunately the boars' teeth were....fresh. REALLY fresh. Not bloody-gory fresh, but ...fresh. It is surprisingly hard to wrap something when you're trying to not touch it.
--The Pick of Destiny: apparently an actual prop from a rather terrible movie. 
--Electronic car key fobs. Amusingly enough, I ended up doing this for two generations of one family, leading me to wonder if car-key-fob destruction was somehow genetic.
--Wobbly leg on a chair. I sort of lashed it to the chair seat.
--a car. We had a car die on site once, with ten minutes to opening (not cool for a ren faire.) Someone had a truck, someone else had tow chains, but no one had an s-hook. So I made one out of 4-ga copper wire.
--someone's hair. It was for a Pippi Longstocking costume. We cannibalized a wire coathanger and then wired her braids to it.
--zipper tabs--about a million of them. That stupid flippy tab breaks all the time and I've done wire and a bead to replace them more times than I can count.
--hinges on a cupboard. The hinge pin broke. *shrug*
--sunglasses. The screw went where glasses screws go, and...yeah.
--a travel grill lid. Hinge pin again.
--several folding chairs.
--a tent. Hinges again.
Duct tape is always an option, but wire works, y'all.
