There are a wide variety of trees and plants that can provide raw material to make cordage. Using this technique as shown, will enable you to make your own cordage.
The best preparation to not to have to make your own cordage would be to carry it with you at all times.
550 parachord is an excellent resource to have on you should you find yourself in a survival situation or for any other situation that would require string.
550 parachord has a strong, hollow, nylon outer layer filled with many smaller nylon strings that can be pulled out and used individually. Parachord has hundreds of uses, such as: replacing a shoe string; making a bow; making a shelter; making a tourniquet; making traps and snares, etc.
In a later segment I will demonstrate how to make a parachord survival bracelet that can be worn on the wrist, providing the wearer with constant access to string when needed.
Stay Prepared! Stay Alive!
