Waxed Cotton Craft Jewelry Cord. This waxed braided cotton cord is soft, flexible, and strong against the elements. Waxed cotton cord holds knots very well and is used often in the popular friendship bracelet designs. The wax on the cord helps protect against fraying and deterioration, which helps beads easily slide onto the cord for stringing. All of our colored cords have been sealed after the dyeing process to prevent the transfer of dye from the cord to your skin or clothing. Our waxed cotton cord is sold by the yard, volume discounts are available.
