most hardware stores will carry small rolls of copper,brass, and annealed steel (bale'n wire) in various guage sizes . I was tying vast amounts of jigs the pevious two years and needed to step up tying speed . I machined out one side of my jig mold to accept a 4" piece of black annealed steel wire that was then molded into the jighead . Having the wire anchored in the head made tying jigs much easier . Hold the rubber strips on with one hand ,make a couple wraps pulling tightly on wire using pliers with the other hand, and snip off tag end of wire . The wire holds firm and even though its steel wire it doesn't rust . I'll never go back to thread again!
