Mostly wrapping and tucking. I can usually work the tail of the wire in so it won't be troublesome. If it has a pokey edge, sometimes you can get a teeny tiny file in to take that down, or something small and pointy to tuck it where it sent bothersome.
If I really need soldered, I'll make sure of the type of metal and let my guy have at it. He has all of the equipment for small wire soldering, as he does work on electronic stuff in vehicles since he is a mechanic. He has also welded a thing or two. Braised as well...
I find I am a little too wobbly for my linking to mess with small stuff and fire.
He really recommends a magnetic holder for soldering tiny stuff, that way both of hands are free to work on stuff. He got them from NAPA and they are listed as a magnetic soldering clamp. http://m.napaonline.com/tablet//parts/PartDetails.aspx?Id=SER774025_0120223323
. You can check them out on the NAPA page there. I keep thinking about getting one just to hold stuff in place and free up another hand.
