Now, each cord you use will have different characterisics unique to that type, and the shoelaces I use for my examples are no where near as slippery as most decorative cord choices, so I had to try this knot again in a more standard cord selection, in this case 3mm nylon satin cord. For a button, I would definitely want to use nylon or polyester over rayon as they are much more durable materials, able to deal with constant handling, wear and tear much more gracefully than rayon. Even so, nylon satin cord is far more slippery than the shoelace, and in order to get proper tension on the centre, pretty much all the slack had to be pulled out of the ears, although strangely enough as can be seen in the pictures, one ear was more stable than the others. Of course, if you tightened carefully and then reinforced the centre structure with thread, you could have larger ears if you wanted to.

To finish the set, here’s the stem view of the knot.
