I found a use for those pesky broken pot melts. Cut em up and make pendants out of them. But what I need to finish them is something to hang them from. My neighbor lady had a spool of black shiny string. She doesn't remember where she got it or what it's called. There is no marking on the spool. It just reads 100 feet. I traded her a pendant and three feet of string for the spool. But it doesn't go very far and I need more. I've searched some sights that sell jewelry making supplies and didn't have any luck. I also searched on Google for nylon cord, nylon string, satin cord, and satin string. The search for satin string brought up 98,000 sights all trying to sell me satin string bikinis.

SO, can somebody please help me out here, what is that black string looking stuff called that is pictured above, and where can I get it?
Thanks, Randy
