How Natural Cordage Works
Natural cordage is made by twisting plant fibers in one direction, then wrapping two bundles around each other in the opposite direction. The opposing twists lock the fibers together through tension — no glue, no tools, just physics. This reverse-wrap technique works with any long plant fiber: stinging nettle, dogbane, milkweed, yucca, iris leaves, cattail, or inner bark strips from basswood, willow, or cedar. Quality of the cordage depends on the quality of the fiber preparation.

Harvest and Ret the Fiber
Harvest stalks in fall, then soak or dew-ret to loosen the fiber bundles.
Harvest and Ret the Fiber
Harvest dried stalks of stinging nettle, dogbane, or milkweed in autumn after plants have died back. The fibers are in a thin layer beneath the outer bark. Ret the stalks by soaking in water for 1 to 2 days or leaving on damp ground for several weeks — this decomposes the pith and loosens the fiber bundles. After retting, split and peel away the fiber from the stalk.
Process Fiber to Remove Pith
Crush the retted stalk and scrape away the woody pith leaving only fiber.
Process Fiber to Remove Pith
Crush the retted stalk lengthwise between two rocks or roll under your foot. Peel away the outer bark and scrape the inner woody pith off the fiber bundles using a thumbnail or smooth stick. The goal is long, clean fiber bundles without pith or bark fragments. Wet fiber is much easier to clean than dry. Keep fibers damp during processing.
Begin the Reverse Wrap
Split fibers into two bundles and begin twisting and wrapping.
Begin the Reverse Wrap
Divide your fiber into two equal bundles. Twist one bundle clockwise between thumb and forefinger until it kinks. While maintaining that clockwise twist, wrap the twisted bundle counterclockwise around the second bundle. Now twist the second bundle clockwise and wrap it counterclockwise over the first. This alternating twist-and-wrap locks the structure. Work toward you along the fiber length.
Add New Fiber as You Work
Splice in new fiber by overlapping the old with new near the end.
Add New Fiber as You Work
When a bundle becomes too short to work (about 2 inches from the end), lay a new fiber alongside the existing one overlapping by 3 to 4 inches. Continue wrapping — the overlap creates a mechanical join that holds under tension. Stagger the joins in each bundle so they do not occur at the same point in the cordage.
Good Beginner Fiber Sources
Stinging nettle — excellent, very strong, widely available
Dogbane — traditional, strong, aromatic fiber
Milkweed stalks — commonly available, good first fiber
Cattail leaves — easier to process, slightly weaker
Iris leaves — widely available, best when dried and rewetted
Keep Fiber Slightly Damp While Working Dry fibers are brittle and break under the tension of twisting. Keep a small bowl of water nearby and wet your fingers as you work. Fiber twisted when damp holds the twist when it dries, producing firmer, stiffer cordage. Overly wet fiber is slippery and harder to control — aim for damp, not dripping.
