I have used a couple of types of Velcro cable ties in the past.  The best ones have hooks all along one side and fuzz all along the other with  a slot in the top, so you can loop it around the cable at one end so it stays attached even when the cable is unwrapped.  These have hooks only on about an inch or two at one end of the tie.  You have to wrap it carefully (and not particularly tightly) around the cable bunch until you get to then end with the hooks.  If you unwrap the cable the tie falls off.  These a just considerably more annoying to use than the type I first described.  One other review mentioned these work best in more permanent installations where you aren't going to be undoing them regularly.  True, but plastic zip ties and twist ties also work for this at a fraction of the cost.
