Griffin 100% silk bead cord is a great stringing material, because it stretches less than other synthetic materials, and this bright green color is sure to make a bold addition to your jewelry designs. Silk is the traditional stringing material used by beaders for centuries, prized for its soft, smooth nature. Each 100% silk bead cord has a twisted stainless steel needle at the end to save threading time. Doubling the thread is unnecessary, and the cord can be easily knotted because the thread has the correct twist. Each card has approximately 79-inches of silk cord.
