Lovely! While I can see that this is solder together, I can't help thinking that you could wire this all together if you wanted to make one similar and can't solder. You would have to make the piece individually, but it could be done.
great free tutorial from instructables. Celtic knot pendant. calls for soldering, but if you leave the ends a little longer, you can just create your own loop. technique note: filing notches to fold wire neatly
