Silk thread by Griffin is a smooth, glossy thread that has been traditionally used for pearl bead stringing and knotting between each pearl. Silk thread is packaged pre-attached to a thin twisted needle for ease of use. The thread has the correct twist, so there is no need to double the thread and it is easy to knot. Each card contains 2 meters (about 6.5 feet) of thread. Size #2 is approximately 0.45mm thick, available in White. Sold by the package.
