Another way to get nice ear loops all the way around your polygonal knot is to tie it button style (knobby thing that you could put through a button hole or button loop formed on top of a short stem). There are more flower-ish buttons to follow, but whether the transformation is extensible to the entire family of flower knots is a matter for further research. Now, the knot here (see left) is tied with some nice ear loops because I could, but in practice you probably want the ears tight against the body of the knot so that they don’t catch and the cord doesn’t wear out prematurely.

I’ve included a scan of the back side (see right) so you can clearly see where the ends are.

Now, I’ve mashed the whole thing flat for better scanning, but that’s not the way a button is supposed to be, here’s a view of the knot tilted on it’s side (see left). I was debating whether or not to bind the ends as would be done if you were really using it for a button, but figured you could imagine it. 8)
