A simple leather eight sided loom with a hole in the center. A fill the gap loom. Or also a Kumihimo loom style.

Kumihimo cord was first created by a form of finger-loop braiding. Later tools such as the marudai and the takadai were employed to make more complex braids in shorter time. The most prominent historical use of the cords was by samurai as both a functional and decorative way to lace their lamellar armour and their horses' armor (barding). Kumihimo cords are now used as ties on haori jackets and obijimes, which are used for tying on an obi (kimono sash).

A modern kumihimo disk made of firm but flexible foam plastic with notches can also be used as a portable marudai. The disks have up to 32 notches that create the tension that is usually created by tama on a marudai. The disks are convenient but are not as versatile as the marudai. On a marudai, any thickness or amount of string can be used, but on a disk only 32 or fewer strand braids can be made. Also, marudai can make many types of braids, such as flat, four sided, and hollow. There are also rectangular foam cards, especially suitable for making flat braids.

I use a leather made eight sided disk with a slot center of each side and a center hole.

To set it up. I take seven strands and tie one group of ends in a knot and tread it through the center hole. Then place the strands on in each slot. This leave one empty. To start the weave you hold the empty slot toward you. count up three strands counter clock wise from the empty slot. then take that strand and place it in the empty slot. Rotate the disc's empty slot toward you and repeat. As you continue push the center through the hole and the cord will start to appear.

I have found that depending on how the strands of color are placed will dictate a pattern. I will try to show as I make cords the placement of cords and the pattern that is made.
