This is one of the fastest methods we've found for neatly gathering multiple cords and cables. You get 15' of 5/8" diameter zipper-like plastic tubing, easily cut to length with scissors, plus a “zip” key for threading cables.
Simply clasp the hinged zip key around the cables you want organized, and pull the key through the zipper-like tubing. As the key travels down the tube, it opens the zipper and inserts the cords. As the key passes, the zipper automatically closes again, enclosing the cords. You can add or remove cables any time, or branch individual cords off at any point along the length.
Great for organizing cords around computers and entertainment centers.
