This is my first attempt at making the Square Ring. I used a wrap on the other side. My knuckles are big however, I think I made this ring too big. It's better than the squiggly one I made. I don't know why but I had trouble with that one. I think it's the kind of wire I'm using not to to mention it doesn't say gauge on the spools. Plus keeping pliers in same place. I think this is 18 gauge or close. The type of base metal I'm not sure.
