Chinese button knot is essentially a diamond knot where the lanyard loop is shortened to a minimum, i.e. tightened to the knot itself. There emerges therefore only two lines next to each other from the knot: the beginning and the end. The knot has traditionally been used as a button on clothes in Asia, thus the name.
There is however a tying method that does not require a carrick bend as a first step, and does not produce a lanyard loop that needs to be reduced when used as a button. This method provides just the button, a spherical basket weave knot, in the style of Turk's head knot or diamond knot.
