Knots and Cordage
Why This Matters Rope is one of the oldest human technologies and one of the most critical. Without it, you can’t build a shelter, set a trap, fish, climb, haul, or bind a splint. Modern rope is everywhere in the old world — paracord, clothesline, electrical wire — but it runs out. Knowing how to make cordage from plants and tie knots that hold under load is a foundation skill that unlocks almost everything else in survival.
What You Need
For Cordage
- Plant fibers: inner bark of dead branches (basswood, cedar, willow), dried grasses, stinging nettle stalks, cattail leaves, yucca leaves, or any long fibrous plant material
- Water (soaking softens fibers)
- A flat rock or your thigh (for rolling fibers)
For Knot Practice
- Any piece of rope, cord, shoelace, or vine (1–2 meters)
- A pole, branch, or post to tie to
- Your hands and patience
Part 1: Making Cordage from Plant Fibers
Harvesting Fibers
Step 1. Find fibrous plant material. The best sources are:
- Inner bark of dead (not rotting) branches — peel the outer bark, strip the inner layer into long ribbons
- Dried grasses — long, tough species work best
- Stinging nettle stalks — crush the stalk, peel away the outer fiber strips (wear gloves or use cloth)
- Cattail leaves — dry them first, then split into strips
Step 2. Process the fibers. Strip them into the longest, thinnest strands you can manage. Remove woody bits and weak sections. You want fibers that are flexible but strong when pulled.
Step 3. If fibers are stiff or brittle, soak them in water for 15–30 minutes. This makes them pliable and easier to twist.
The Reverse Twist Method
This is the fundamental technique for turning loose fibers into strong rope. Every piece of handmade cordage in human history uses some version of this.
Step 4. Take a bundle of fibers (about pencil thickness for a first attempt). Fold the bundle roughly in half, but offset — one side should be about 5 cm (2 inches) longer than the other. This staggering prevents both strands from ending at the same point.
Step 5. Pinch the fold point between your thumb and index finger. You now have two strands (called plies) hanging down.
Step 6. Twist the ply closest to you away from you (clockwise if you’re right-handed) between your thumb and fingers. Give it 3–5 tight twists.
Step 7. While keeping that twist tight, bring that ply toward you and cross it over the other ply. The twisted ply is now the far ply, and the untwisted ply is now closest to you.
Step 8. Repeat: twist the near ply away from you, then cross it over. Twist, cross. Twist, cross. Maintain tension so the twists lock against each other.
Step 9. Adding fibers (splicing in). When one ply gets short, lay a new bundle of fibers alongside it, overlapping by at least 8 cm (3 inches). Twist them together as one. Stagger your splices — never add fibers to both plies at the same point, or the rope will have a weak spot.
Step 10. To finish, tie an overhand knot in the end, or twist the remaining fibers tightly and tuck them back into the rope.
Strength test: Good plant-fiber cordage the thickness of a pencil should hold 10–20 kg (22–44 lbs). For heavier loads, braid three ropes together.
Part 2: The 8 Essential Knots
Learn these eight knots and you can build shelters, set traps, haul loads, and fish. Practice each one until you can tie it with your eyes closed.
Knot 1: Bowline — The “Rescue Loop”
Creates a fixed loop that won’t slip or tighten under load. The single most useful knot.
Use it for: Rescue loops, tying rope around a person or object, anchor points.
Step 1. Hold the rope with the free end (working end) in your right hand. Form a small loop in the standing part (the long side) — the free end crosses over the top.
Step 2. Pass the working end up through the loop from underneath (the rabbit comes out of the hole).
Step 3. Pass the working end behind the standing part (the rabbit goes around the tree).
Step 4. Pass the working end back down through the same loop (the rabbit goes back in the hole).
Step 5. Pull the working end and standing part to tighten. The loop should be fixed — it won’t slip tighter or loosen.
Memory aid: “The rabbit comes out of the hole, goes around the tree, goes back in the hole.”
Knot 2: Clove Hitch — The “Quick Attach”
Ties a rope to a pole or post quickly. Good starting knot for lashings.
Use it for: Attaching rope to poles, starting/ending lashings, temporary tie-offs.
Step 1. Wrap the rope once around the pole.
Step 2. Cross the working end over the standing part and wrap around the pole again.
Step 3. Tuck the working end under the second wrap (under the X you just made).
Step 4. Pull both ends to tighten.
Warning: The clove hitch can slip under varying loads. Always back it up with a half hitch for critical applications.
Knot 3: Taut-Line Hitch — The “Adjustable Grip”
Creates a loop that slides to tighten but grips under load. Perfect for tent guy lines.
Use it for: Tent and tarp guy lines, adjustable tie-downs, clotheslines.
Step 1. Pass the rope around a stake or anchor point, creating a loop.
Step 2. Bring the working end inside the loop and wrap it around the standing part twice, working away from the anchor.
Step 3. Bring the working end outside the loop and wrap it around the standing part once more, above the first two wraps.
Step 4. Tuck the working end through this last wrap.
Step 5. Tighten. Slide the knot along the standing part to adjust tension. It grips when pulled from the loop side.
Knot 4: Square Knot (Reef Knot) — The “Binding Knot”
Joins two ends of the same rope for binding. Simple and flat.
Use it for: Tying bandages, binding bundles, finishing lashings.
Step 1. Hold one end in each hand. Cross right over left and tuck under.
Step 2. Now cross left over right and tuck under.
Step 3. Pull all four strands to tighten. The knot should lie flat with both loops on the same side.
Critical: Right over left, THEN left over right. If you do the same direction twice, you get a granny knot — it slips and jams. Never use a square knot to join two ropes under load; use a sheet bend instead.
Knot 5: Figure-8 Knot — The “Stopper”
A bulky knot at the end of a rope that prevents it from pulling through a hole or device.
Use it for: Stopper at rope ends, preventing rope from unraveling, base for figure-8 loop.
Step 1. Form a loop by crossing the working end over the standing part.
Step 2. Bring the working end under the standing part (going all the way around).
Step 3. Pass the working end through the original loop from the top.
Step 4. Pull to tighten. The knot looks like the number 8.
Knot 6: Trucker’s Hitch — The “Mechanical Advantage”
Creates a pulley-like system for extreme tightening. The most powerful tying knot.
Use it for: Securing loads, tightening tarps, ridge lines, hauling.
Step 1. Tie one end of the rope to a fixed point (use a bowline or clove hitch).
Step 2. At the midpoint of the rope, form a small fixed loop (use a slip knot or alpine butterfly — the simplest is twisting a small loop and pulling a bight through it).
Step 3. Pass the working end around the second anchor point (the thing you’re tying down to).
Step 4. Thread the working end up through the loop you made in Step 2.
Step 5. Pull down on the working end. The loop acts as a pulley, giving you roughly 3:1 mechanical advantage. Pull it as tight as you need.
Step 6. Lock it off with two half hitches around the standing part.
Knot 7: Sheet Bend — The “Rope Joiner”
Joins two ropes of different thickness. More reliable than a square knot for this purpose.
Use it for: Joining ropes of different sizes, extending rope length, net making.
Step 1. Form a bight (U-shape) in the thicker rope. Hold it in one hand.
Step 2. Pass the thinner rope up through the bight from underneath.
Step 3. Wrap the thinner rope around the back of the bight (around both legs of the U).
Step 4. Tuck the thinner rope under itself (under its own standing part, but over the bight).
Step 5. Pull all ends to tighten. Both free ends should exit on the same side of the knot.
For slippery or mismatched ropes, wrap the thinner rope around twice — this is a double sheet bend and is significantly more secure.
Knot 8: Timber Hitch — The “Drag and Haul”
Grips a log, pole, or cylindrical object for dragging or hoisting. Tightens under load, releases instantly.
Use it for: Dragging logs, starting lashings on round objects, hoisting.
Step 1. Pass the rope around the log or pole.
Step 2. Bring the working end around the standing part.
Step 3. Twist the working end back around itself three or more times (not around the standing part — around the section between the log and the standing part).
Step 4. Pull on the standing part. The twists cinch tight against the log. Add a half hitch further along the log for straight-line pulling.
Part 3: Square Lashing — Building with Poles
Square lashing binds two poles at a right angle. This is how you build frames, shelters, tables, racks, and towers from sticks and rope.
Step 1. Start with a clove hitch on the vertical pole, just below where the horizontal pole will cross.
Step 2. Place the horizontal pole on top of the vertical pole at a right angle.
Step 3. Wrap the rope: go over the horizontal pole, behind the vertical pole, over the horizontal pole on the other side, behind the vertical pole. You’re making a square pattern. Pull each wrap tight.
Step 4. Make 3–4 complete wrapping turns, keeping them tight and parallel.
Step 5. Frapping turns: Now wrap the rope between the two poles (perpendicular to your wrapping turns), pulling the lashing even tighter. Make 2–3 frapping turns.
Step 6. Finish with a clove hitch on the opposite pole from where you started.
Step 7. Test by pushing the joint. It should be rigid with no rotation. If it moves, add more frapping turns.
Common Mistakes
- Not maintaining tension while tying. Loose knots fail. Every wrap should be pulled snug before the next one.
- Using the wrong knot for the job. A square knot to join two ropes under tension will slip and fail. Use a sheet bend. Match the knot to the task.
- Splicing fibers at the same point. When making cordage, never add new fibers to both plies at the same location. Stagger splices by at least 5 cm.
- Ignoring fiber quality. Rotten, brittle, or too-thin fibers make weak rope no matter how well you twist. Test fibers by pulling before committing to a long rope.
- Tying the granny knot instead of the square knot. Same direction twice (right-over-right or left-over-left) gives you a granny knot that slips and jams. Remember: right over left, then left over right.
- Skipping frapping turns on lashings. Wrapping turns alone make a loose joint. The frapping turns between the poles are what cinch everything tight.
What’s Next
