Beadwork is the art or craft of attaching beads to one another by stringing them with a sewing needle or beading needle and thread or thin wire, or sewing them to cloth. Beads come in a variety of materials, shapes and sizes. Beads are used to create jewelry or other articles of personal adornment; they are also used in wall hangings and sculpture and many other artworks. Beadwork techniques are broadly divided into loom and off-loom weaving, stringing, bead embroidery, bead crochet, and bead knitting.
