So get 9 of the 4 foot strips and rip them in half (LENGTHWISE!) This is were the nylon rope comes in! Make a little loop out of the tape and put it around the end 4 footer. tape it with the nylon rope so that the rope goes all the way down the half strip.Then tape around the rope. Get nylon rope and place it on the end four footer and put duct tape on top. then do that with all the edges.
