All the kumihimo braids are made with the traditional 8-cord round spiral design. For this first necklace, I used a wonderful focal bead by Harold Williams Cooney. The bead is part of his Colorado Trade Bead series. The magatamas I used are the 4 x 7 mm matte metallic patina iris and matte metallic khaki iris. The Sea Urchin necklace design itself is featured in Karen de Sousa’s book, Braiding with Beads.
