Not having cordage to rely on severely cripples you as a survivor. In the past, people merely made their own cordage when they didn't have any on them. This is a valuable trick even today, and you can learn the simple method below.

This really is an easy trick to learn. It just takes patience and a little bit of practice and before you know it, you'll be cranking out foot upon foot of high-quality cordage to use for traps, shelters, and even to make repairs to your gear. Of course, some materials work better for cordage than others, so you should do some research on the plants in your area to determine which ones will serve you best for this purpose.
