I do it the same way I did in the army. Cut the ends off of a used chemlight (glow stick) wash it out (be careful of the broken glass). Wrap the tape around the tube. Cut the tube to the with of the tape. Use a small piece of the tube and some five fifty cord to make a carrier for the tape. Basically a loop of cord with the small piece of tube tied on it. Then thread it through the center of the tube with the tape. The small piece of tube only serves to keep the tape tube from falling of the end. The tape tube will unwind freely when you are holding the ends of the cord and if you made the loop big enough you can attach it to your pack by using the loop at the other end and threading the spindle through it.
