Two braid structures are the basis of this kumihimo study: 8-element Edo Yatsu Gumi and 16-element Naiki. Using two different colors of silk, braiders will investigate the different effects when a flat Naiki braid divides into two round Yatsu Gumi cords. If the cords are the same length, they form small openings between them when rejoined to Naiki. If the cords are different lengths, they form loops or picots which can appear on the same edge or zig-zag from side to side.
