I use insulated magnet wire to do the wraps, and dip the ends in lacquer thinner to very slightly melt the insulation. It will still break the bonds enough to flex like a spring side-to-side but has a bit of connection to keep it from unwinding. I have also use a thin coat of Ambroid, too, doesn't stiffen it too much, or in many cases, nothing. DO NOT solder it and do not use any significant coat of epoxy.
