It wouldnt have looked or felt like wire. It wouldnt be very round. Hammer a thin plate then slice a spiral with an obsidian knife. You wont by making knots with it, just wrapping it around molds. But i would think that wet cord or sinew would have worked just as well. Or they could put the mold in the ground, letting packed dirt keep the two halfs together.
