There have been a couple of blog posts re: cold connections. I began my 'metal' art by working in wire, from there I moved to incorporating some sheet but working all cold. (then I moved to a torch for headpins and reticulating and from there it was an easy jump to soldering...lol)

Anyway, I still maintain a network of friends who enjoy working with wire so I try to come up with some designs using cold connections that might intrigue them into metal sheet in addition to the wire they work with. Here is a ring that I came up with that is all cold connected. There are some kinks to work out - but its a start. :)
