To create a button and loop closure:
On one side of the beadwork, add a new thread. Coming out of a bead near the center of the edge, pick up a seed bead, a button or bead, and another seed bead. Skip the last seed bead and pass needle and thread back through the button or bead and the first seed bead. Weave into the beadwork and back through the button if desired. Finally, weave needle and thread into the beadwork, knot, weave the end in a bit more, and trim close to the beadwork.
