Unlike the inline square flower knot (see left), Ashley #588, a rectangular knot is not simply the 1x2 mystic knot (see right) with one end passed through the body of the knot to give a half-hearted extra ear (although it could certainly be done that way). The pass-through occurs earlier and still has no structural support, so the ears still need to be either “closed” or sewn in order that casual handling not destroy the knot.
