I love these. I use them on cords all over the house, both those in use and stored. They come with the fuzzy Velcro material the length of one side, and the hooks on an inch on the end of the other side. I just wrap them tightly around the cord until the hook material is in the right place. It's not a difficult concept. If the Velcro hooks ran the length of the other side, it would probably be very difficult to remove the tie when you needed to.
