Griffin Silk Bead Cord is the most popular choice when tying knots between beads in the traditional pearl-knotted style or any design in which visible cord is an integral part. A twisted stainless steel beading needle is attached to one end of the 100 percent silk cord, making stringing fast and easy. Griffin Silk Bead Cord in size 6 is approximately 0.70mm (0.027 in.) in diameter and suitable for 0.8mm bead holes and larger. Approx. 79 inches (2 meters) of thread per card.
