For a high quality neutral stringing material, use this 100% silk grey Griffin silk cord. Griffin uses a specific manufacturing process for their silk cord that puts just the right amount of tension on the thread and avoids tangling and knotting. This No. 10 silk cord works well with beads featuring a 1mm hole size. You can use this silk cord in a knotted necklace or in a mixed media project. Each two-meter silk cord has a twisted stainless steel needle at the end to save threading time.
