10 metre length of nylon knotting cord, size 9 (approximately 0.7mm thick). This cord is a 3 ply twisted thread, and great for working with seed beads, kumihimo and other knotting projects. Used as an alternative to silk, nylon cords don't tend to have as much stretch as their natural counterpart. Available in black, dark red, rainbow or white. This thread works particularly well with the thread zapper - due to its nylon nature, the thread zapper will not only cut, but melt the ends of cord together, making it easier to add ends etc.
