I double the cables over until they're short enough, and then tie them into a loose half knot.

No fasteners to wish for, or to fail.

Both ends of every cable are always next to each other for identification at a glance.

Different cables cannot tangle with each other in a box.

There are no axial twists imparted into the cable.

(Stage hands hate this technique, but this isn't stagecraft.)
