Usable rope can be bent, turned, as well as woven from virtually any type of thin, fibrous material, including plastic shopping bags, ribbons, hair and plant fibers. As a matter of fact, the Incans constructed grass and natural fiber bridges that spanned huge rivers and gorges. These bridges sustained the weight of not only people but of wheeled carts and animals. Like a lot of the survival skills, the devil is in the details when it comes to improvised cordage. The process of twisting, pinching, and weaving natural fibers into cordage is called a reverse wrap, and this is a hack created by primitive man many years ago.
