What I did was use the Velcro dots. I used wide satin binding tape, like a quilter might use, and after cutting it to the right length, laid it out on the floor. I then laid my 'pipes on top of the ribbon, with the cords centered on the ribbon. I spread the drones apart as far as the cords would go, then attached a Velcro dot (above and below the cord) to the ribbon, on either side of the drone. It takes 4 each of the two Velcro pieces for each drone. Then I took the mating piece of Velcro and pressed it into the ones I had just attached, so the sticky side of the Velcro dots was facing up. I then laid the top piece of ribbon over the bottom one, sandwiching the cord and drones in between the two ribbons. I pinned one end of the ribbons together, then squeezed the ribbons together, so the sticky side of the Velcro would adhere to the top ribbon.
Here's a picture of red and white ribbons.

I made a pair each of red, white, black and light blue ribbons, and they're interchangeable.
