The most simple knot, the overhand knot, in its most common form, is an
ugly knot ... I do not wish to imagine how the world would look like if the objects had such a form...

However, the overhand knot is but an interrupted trefoil knot - so, in this balanced, 3-symmetric form, it is a beautiful object. I tried to figure out the most symmetric bend made by two interweaved trefoil-knot-looking overhand knots - and so I tied the decorative bend shown at the attached pictures. The reader can compare it with a couple of similar knots, shown at (1).
At the centre of the knot, the 3 +3 = 6 stands at the core of the two trefoil-knot looking overhand knots meet each other at a
hexagram (2) - so I had called this bend "the Hexagram bend". If it is also known with another name, please let me know.
( At the pictures I show the original decorative bend. If one will connect the same-colour free ends, he will get a nice 6-leave rosette.)
