It started as a mens bracelet. Wax cotton cord, with sterling silver beads. And a cool round coin, about 50% the size of a dime. I also used a mini skull. Also made of sterling silver. I believe both the bracelet and the skull are made by GOOD ART HOLLYWOOD. I found them both on closeout. COOL STUFF. Anyway, I didn't trust the strength of the wax chord, so I wove in braided 15lb test fishing line, black, through the entire length of the cord. Then, I used a thicker black poly shoelace, internally reinforced with tons more braided fishing line, sewed the pieces together so that they are still "jangly", and then wrapped it in steel wire for contrast.
Notice, on the right scoop in order to prevent a lot of scratching, I applied an adhesive poly card... It is actually a clear, flexible guitar pickguard, that I cut to shape and applied to the scoop. Hopefully the adhesive will hold it in place for awhile. It 's a KILLER keychain. And the long string dangles out of your pocket and helps you pull the key from your pocket. WAY COOL.
