One axion of lightweight, efficient backpacking is to employ as many multiuse items as possible. A cordage bracelet is basically serving only as a stockpile of cordage and hence is relatively inefficient Various items one would carry on a typical hike includes or can be crafted to include cordage that can be adapted for shelter construction and other uses.

For one thing, I like to carry lanyards to which I can attach knives and other tools if I am working in exposed locations where tools, etc. would be lost if dropped. These are basically lengths of paracord about three feet long, easily available for use. I am often hiking with my dog, and i carry a leash. Someday I should fabricate a six foot leash from paracord - that would provide lots of cordage in an emergency. There there are always shoelaces (and spares) as well as the neck cords for my compass and whistle. These can be pressed into service if necessary.

Of course, if I am carrying any climbing gear, I will probably have all the cordage I could possibly use. What other items could serve as emergency sources of cordage?
