This skill set shows you several basic ways to work with jump rings and assemble chains just by opening and closing them. No need to solder to make these complex, intricate, ancient chains!
How to Make Your Own Jump Rings
Only make your own jump rings when you've got the correct tools for the job, and you need to do so because of scale or shape constraints. Jump rings are cheap, and come from a million different suppliers - I usually use www.riogrande.com. But, if you need a particular shape, size or material and can't find it, you can use this tutorial to help you build your own.
How to Open and Close a Jump Ring
This may seem like a small thing, but opening and closing a jump ring correctly will really keep your craftsmanship neat and tidy in these chains. I agree with this tutorial in its twisting motion, but would strongly suggest you hold your pliers parallel to the split in the jump ring, rather than perpendicular as shown. The more of the jump ring you cover, the less likely you are to warp the shape of your jump ring during the opening and closing process.

Chain Maille Patterns
Building Chain Maille can be frustrating until you get the hang of it. Here's a brief video from my Craftsy.com jewelry class, which shows me adding a few links to a row of chain maille. Hope it helps!
