The wires of electrical appliances, having a large length, it is easier to keep folded in a coil. And to lock them in this position, you can make a special clamp. For example, from strips of fabric, one end of which is sewn a button, and the other has under it a number of holes. Buttoned such a “strap” does not have to fear that the cord or the hose unwinds. For a large coil it is better to use two or three clamps, putting them in different directions. Under the thin wire as a retainer, you can use any old strap from a wrist watch.
