Seed bead jewelry involves sewing or weaving seed beads, the smallest type of beads, onto fabric or thread. Basic materials include seed beads, thread or wire, crimp beads to attach clasps, and beading needles. Common techniques are the daisy chain, which links beads together in a chain, and ladder stitch, which attaches beads in rows resembling a ladder. Crimp beads are used with wire to hold clasps in place by crimping the bead around the wire using specialized pliers.
