VELCRO Brand 90302 One-Wrap Straps,4-Feet by 3/4-Inch, Black

This stuff is awesome. I use tons of it. Give rolls of it away as gifts. Every cable in my laptop bag & backpack, has this stuff (cut to appropriate length, of only a few inches), holding each cable bunched up & organized. My work tool power cords? Yep, bunched-up, and secured with this double-sided Velcro. Just use scissors & cut off the length you need.
