I was working on the main page for the mystic knot and decided that I really needed to have my own illustration of the ru-yi knot (如意, rúyì, halfway between a 장고매듭, jang-go-mae-deup, and a 가지방석매듭, ga-ji-bang-seong-mae-deup).

Consider your standard square flower knot (see right). The structural centre is distinctly square, which is good. But, you say, there are only three ears. You say, a square knot should have four ears. I say, consider the loose ends to be the fourth ear. You, nevertheless, remain dissatisfied. A square has four sides, should not a square flower knot have four ears?
