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.
