This is a necklace that I made. It is Nickle silver, 20 gauge, cold worked (no soldering), with green glass beads. It is about 27" long. All of the jump rings were hand wound and cut by me. The link style is one that I learned in my Intro to Fine Metals class. Really simple stuff.
I don't have a tutorial for this, but I do have the instructions from my textbook, The Complete Metalsmith by Tim McCreight.
