The Japanese art of kumihimo dates back to the 7th. century. Originally, the cords woven on the maru dai (or marudai) were used to attach the leather plates of armour worn by Samurai warriors. Nowadays, these decorative creations can be used as anything from friendship bracelets to cords on purses to decorative trim on boxes.

Hand-made maru dai, complete with eight tama (spools) and instructions are available from Thomas Frames for $60 (US) plus shipping (actual cost)
