I found this great plastic tubing at the hardware store and bought several feet of it. I was there to get something more practical but I knew I would use it someday. . . you know the feeling!
At any rate, it finally found a place with some hex nuts and metal plated silver tone beads. The large beads I found for super cheap at a craft store. They are plastic underneath so very lightweight, and I am sure it will get a lot of wear! Total cost was about $15, including the chunky silver tone s clasp, some flex wire and sterling crimp tubes.
