The bow knot that won't budge -[ SoS ]-

A bow knot, or shoelace knot, tied using the double-knot method, a technique intended to minimize the possibility of the knot loosening prematurely. (This WikiHow page shows how it's done, although I learned the technique many years ago from another website I don't recall and which may no longer be around.)

 

This habit was the result of shoes with shoelaces that, despite my best efforts to cinch them tight after tying them the traditional way, had an annoying habit of loosening. Once I used the double-knot technique, the laces stayed put.
