The ability to make cordage from natural materials is one of the most fundamental survival skills. Rope and cord have thousands of uses in a wilderness setting: building shelters, setting traps, making fishing line, lashing tools, creating snares, bundling firewood, hanging food bags, and improvising repairs. Without some form of cordage, many other survival skills become impossible or impractical.
Natural cordage will not match the strength of modern paracord or nylon rope, but it does not need to.
A properly made two-ply cord from good plant fibers is strong enough for most camp tasks and can be made in any environment where plants grow.
Identifying Good Fiber Sources
The best fibers for rope making are long, strong, and flexible. They come from the inner bark (bast fibers) of certain trees, the leaves of fibrous plants, and the stems of various weeds and grasses.
Inner bark fibers from basswood (linden), tulip poplar, cedar, elm, and willow are excellent rope-making materials.
These trees have an inner bark layer that peels away in long strips and separates into fibers when soaked and worked. Basswood is often considered the gold standard because its fibers are long, strong, and easy to process.
Plant leaf fibers from yucca, agave, cattail, and iris provide strong cordage material. Yucca is outstanding, producing fibers that rival commercial twine in strength. Cattail leaves are widely available near any water source and produce serviceable cord.
Stem fibers from stinging nettle, dogbane, milkweed, and hemp provide some of the strongest natural cordage.
Dogbane and nettle fibers have been used for thousands of years across multiple cultures and produce cord that is remarkably strong for its diameter.
Harvesting and Processing
For inner bark, select a branch or small trunk (avoid stripping bark from living trees unless survival demands it). Make a vertical cut through the outer bark, then peel the bark away from the wood. The inner bark, a thin, flexible layer between the outer bark and the wood, is what you want.
It often peels away in long ribbons.
Soak the inner bark in water for several hours to several days. This process, called retting, breaks down the pectin that binds the fibers together and allows them to separate. The fibers become softer, more flexible, and easier to twist after retting.
For leaf and stem fibers, harvest the longest leaves or stems available. Pound the material gently with a rock or piece of wood to break the outer tissue without cutting the fibers inside.
Then peel or scrape away the soft plant material to expose the inner fibers. Alternatively, dry the plant material first and then work it to separate the fibers.
The Reverse Wrap Technique
The reverse wrap (also called the reverse twist or counter-twist) is the fundamental method for making two-ply cordage. It is simple once you understand the principle and produces strong, even cord with practice.
Start with a bundle of fibers about twice the length of the cord you want to make.
Fold the bundle unevenly at roughly the center, creating two legs of slightly different length. The uneven fold means the splices (where you add new fiber) will not occur at the same point on both legs, which would create a weak spot.
Hold the fold between your thumb and forefinger. Twist the leg farthest from you away from your body (clockwise if the fold points to the left). Then wrap this twisted leg over and in front of the other leg, toward your body.
Now the other leg is the far one. Twist it away from your body, then wrap it over and toward your body.
Continue this pattern: twist away, wrap toward. The individual twist in each leg goes in one direction while the two legs wrap around each other in the opposite direction. This opposing tension is what holds the cord together and prevents it from unraveling.
Splicing: Adding Length
When one leg gets short, you need to splice in new fiber to continue.
Lay the new fiber alongside the short leg with about 3-4 inches of overlap. Continue the reverse wrap, incorporating both the old short fiber and the new fiber into the twist. After a few wraps, the new fiber is locked in and the old short end can be trimmed.
Stagger your splices. Do not add new fiber to both legs at the same point because this creates a bulky, weak spot. Add to one leg, continue wrapping for at least 6-8 wraps, then add to the other leg if needed.
Testing Strength
Test your finished cord by pulling it firmly between your hands. Good two-ply natural cordage about 3mm in diameter should hold 20-40 pounds without breaking, depending on the fiber source and the quality of your twist. If it breaks easily, the fibers may be too short, the twist may be too loose, or the material may not be suitable for load-bearing cordage.
For applications requiring more strength, make thicker cord by starting with more fibers in each leg, or make a larger rope by using two or more finished cords as the "fibers" in a second round of reverse wrapping. Two-ply cord reverse-wrapped with another two-ply cord creates a four-ply rope with significantly more strength.
Practice Makes It Practical
Natural cordage making is slow at first. Expect to spend 20-30 minutes making your first few feet of cord. With practice, the speed increases dramatically. Experienced cordage makers can produce serviceable two-ply cord at a rate of several feet per hour, which is fast enough to be useful in a survival situation.
The best way to learn is to practice at home with readily available materials. Jute twine from a hardware store mimics natural fibers and lets you practice the reverse wrap technique without needing to harvest and process plant material. Once you have the technique down, take it outside and try it with actual wild fibers.
