Quick Answer
For cordage making, the best parts of a plant are typically the stems, branches, and leaves. These areas tend to be strong, fibrous, and easily harvestable. Look for plants with woody or semi-woody growth.
Choosing the Right Plant
When selecting a plant for cordage, consider its growth habits, fiber content, and availability. Ideal plants are those with strong, flexible stems that can be harvested without causing damage to the plant. Examples of suitable plants include nettle (Urtica dioica), cattail (Typha latifolia), and milkweed (Asclepias spp.). Look for plants with a diameter of at least 1/4 inch (6 mm) for optimal cordage production.
Harvesting and Preparing Plant Material
To harvest plant material, use a sharp knife or pruning shears to cut the stems at a 45-degree angle. This helps prevent water from collecting and promotes healthy regrowth. Remove any leaves or flowers from the harvested stems, as these can be brittle and prone to breakage. For plants with a high silica content, such as nettle, boil the stems in water for 30 minutes to 1 hour to break down the silica and improve the fiber quality.
Processing and Twining
To create cordage, start by stripping the fibers from the plant material using a technique called “decortication.” For example, use a sharp knife or a stone tool to scrape off the bark and any excess plant material. Then, twist the fibers together to create a strong cord. For a more durable cord, twist three to five strands together, and then twist the resulting cord in the opposite direction to create a strong and reliable twine.
