Is it Possible to Create Water-Resistant Cordage with Bast Fibers?

April 5, 2026

Quick Answer

Yes, it is possible to create water-resistant cordage with bast fibers through a process called reverse wrap, which involves wrapping the fibers tightly around a core, then applying a natural or synthetic sealant.

Creating Water-Resistant Cordage

To create water-resistant cordage with bast fibers, start by harvesting and processing the fibers. For nettle or flax, for example, separate the fibers from the stems and remove any debris or excess material. Then, cut the fibers to the desired length, typically around 12-18 inches.

Reverse Wrap Technique

The reverse wrap technique involves wrapping the bast fibers around a core material, such as a wooden dowel or a piece of bone. Begin by wrapping two or three turns of the fibers around the core, then apply a thin layer of natural sealant, such as beeswax or plant resin. Continue wrapping and applying sealant in layers, working your way up the core. For a 6-foot cord, aim for 12-15 layers of wrap and sealant. This process creates a durable and water-resistant cord that can withstand exposure to moisture.

Tips for Enhanced Durability

To further enhance the durability of your cordage, consider adding a few drops of natural oil, such as linseed or coconut oil, to the fibers before wrapping. This will help to repel water and prevent the fibers from drying out. Additionally, consider using a core material that is resistant to moisture, such as bamboo or a hardwood. By following these techniques and tips, you can create a high-quality, water-resistant cordage that will serve you well in a variety of survival situations.
