Does anyone have any idea where to get 1/8" cord, tightly woven, possibly a nylon center to restring my windchimes? They are rather large, the longest pipe being (I haven't measured)approx. 36". I've had these for years, bought them at the Medieval Fair at Ringling Brothers fair grounds one year. The sound is beautiful and the cords are now wearing out where they thread through the pipes. I tried hobby, hardware, marine, the last resort Walmart stores. If you have any ideas Iwould appreciate it.
