Managed to snag a Toho Challenge package while at the 2015 Bead and Button show in Milwaukee, WI. Lovely colours this year. Especially the teals. After faffing about with various hopeless designs I discovered simple is best.
A herringbone rope stitched with teal triangles and gold size 15 seed beads, strung with a cubic right angle weave triangular pendant in metallic dark amethyst seed beads, fire polish crystals, and joined with daggers. Very pretty and wearable. In fact I wear this 18 inch long Toho Triangles necklace quite often.
To see other designs have a look at the Toho Challenge 2015 page.
