Kumihimo  "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 "obijime", which are used for tying on an "obi" ("kimono" sash). A modern "kumihimo" disc made of firm but flexible foam plastic with notches can also be used as a portable "marudai". The discs have 32 notches that create the tension that is usually created by "tama" on a "marudai". The discs 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 disc only 32 or fewer strand braids can be made from thin cord. 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. The foam "kumihimo" disc is lightweight, portable, and significantly more affordable than the traditional "marudai". Braiders can create complex braids up to 24 bobbins and incorporate beads. There are many sizes and shapes of foam discs available. Look for a disc that is sturdy and doesn't bend easily, otherwise the braider will experience uneven tension.
