I use wire on my chain necklaces. You can order gold-fllled or silver, and I'm sure there is base metal, but I don't use that. I also order 14k and 10k for some projects, but you want to be sure with that. I like 26 or 24 gauge dead soft because it is easy to use. I use 22 gauge (I think) to create the ehancer/charm rings that I have been making. When I did my really long tin-cups, I did a loop through the chain and did not finish the actual wrapping until it was all together the way I wanted it. Does that make sense? I usually get the wire by the foot, or by the troy ounce depending on who I order it for (something else to Hui on?). You can get it on the spool, but I've never ordered that much. If you get a kink in it, (not often) you use a Sunshine cloth to straighten it. You have to remember that the wire gets harder the more you work it. Anyone else with advice? I don't use jump rings for earrings, I use wire, even with the chain. I also use wire to put clasps on chains. Here is the long tin cup chain (I need to reshoot that, the pearl colors are way better than those pics). I use beads to frame my pearls and to give it a more finished look.
