See Beads are uniformly shaped, spheroidal beads ranging in size from under a millimetre to several millimetres. "Seed Bead" is a generic term for any small bead. Usually rounded in shape, seed beads are most commonly used for loom and off-loom bead weaving. They may be used for simple stringing, or as spacers between other beads in jewelry. Larger seed beads are used in various fiber crafts for embellishment, or crochet with fiber or wire.
