All you need is a single long piece (at least fifteen meters) of sturdy paracord, as well as a clasp for either end. You can also use this technique to make a rifle sling or something else for which you will need a long length of woven paracord. The knot itself is not difficult - just watch carefully and make sure you've given yourself enough time to finish this project. A great project to make for yourself, or the survivalist in your life.
