Round glass beads. String rocaille beads, for example, onto an elastic cord, jewelry wire, or thick thread. Ensure that the thickness of the beading needle and the cord or thread matches the size of the hole in the bead. When weaving, for instance, you often need to thread two strands of wire through each bead. These small glass beads (also known as seed beads) have a long tradition dating back to historical times. The beads are not only used for many different types of Kumihimo jewelry but also to decorate costumes for various cultures around the world. The beads are charming additions to simple bracelets and necklaces. They are also suitable for woven and sewn Kumihimo jewelry or edgings.
