Once again an interesting thread. I use the green plastic coated wire from the garden centre (2 different diameters). Clean off the plastic and you find stainless steel wire underneath. I turn up a couple of toggles similar to those found on duffle coats years ago and just twist the wire into place. As long as you just hold with the finger tips they are fine. I imagine the wire that you use for pyrography might perform better but it would be more expensive!
