Sorry on the confusion. Hardening does not make it springy, it makes
it more scratch resistant, and less pliable, more difficult to bend.
20 gauge is pretty light and you may not feel the difference when
purposefully bending, on rings, I can tell the difference. 20 gauge
is what I use in my woven bracelets, and ear wires, but I have not
made any with AS yet, I will let you know my results, all I can
promise on a time frame is sometime between now and Friday.
