The barrel knot is a compact, cylindrical decorative knot used as a spacer or accent in macrame projects. To tie a barrel knot, you wrap one working cord around a filler cord several times, then thread the working cord back through the center of the wraps to lock the cylinder shape. It is one of the most versatile intermediate knots you can learn — clean enough for modern minimalist work, textured enough to add real visual interest to any piece. This tutorial covers every step, sizing choices, and tips for keeping your barrel knots consistent from start to finish.

What You Will Need
- 3mm or 4mm single-strand cotton cord — single-strand holds barrel shapes cleanly
- 3 cord lengths, each about 100cm (40 inches) to practice
- A macrame board with T-pins to keep your work anchored
- Sharp scissors
- About 20 minutes for your first barrel knot practice session
The 11x15" Macrame Board with T-Pins from Bochiknot is ideal here — the grid lines help you space barrel knots evenly across a row. Use code KNOT10 for 10% off your order.
If you are still building your core knot vocabulary, read the beginners guide to macrame first. Barrel knots will feel much more intuitive once square knots and half hitches are comfortable.
How to Tie a Barrel Knot in Macrame
Step 1: Set Up Your Cords
Pin three cord lengths vertically to your board. The two outer cords are your working cords — these do the wrapping. The center cord is your filler cord — it stays still while the working cord wraps around it.
For your first practice attempt, work with just one working cord and one filler cord. You only need two strands for the knot itself. The third cord is there to simulate a real project where the filler cord is attached to a longer piece.
Step 2: Hold the Filler Cord Taut
Before you wrap, pin or hold the filler cord straight and steady. This is the axis your barrel will form around. If the filler cord droops or bends during wrapping, the finished knot will look uneven. Use a T-pin at the bottom of the filler cord to keep it under light tension.
Step 3: Begin Wrapping the Working Cord
Take one working cord and place it horizontally across the filler cord near the top of where you want the barrel to sit. Begin wrapping the working cord around the filler cord, moving downward with each loop. Keep each wrap snug against the previous one with no gaps between them.
Consistent tension is everything here. Wrap firmly, but not so tightly that the filler cord bunches. Think of wrapping thread around a pencil — that same even pressure.
Step 4: Complete the Required Number of Wraps
Count your wraps as you go:
- 3 wraps — a slim, subtle barrel knot
- 4 wraps — a medium barrel, the most common choice
- 5 wraps — a chunky, prominent barrel knot
Pick a number and stick with it across your entire project. Even one extra or missing wrap will make the knots look inconsistent when placed side by side. Saying the count aloud as you wrap helps prevent losing track.
Step 5: Thread the Working Cord Through the Center
After your last wrap, take the end of the working cord and thread it upward through the center of all the loops — from the bottom of the column of wraps to the top. You are essentially threading the cord back through the tube you just made.
This step locks the wraps and prevents them from unraveling. Use a tapestry needle if the loops are too tight to thread by hand.
Step 6: Tighten the Knot
Hold the filler cord steady with one hand and pull the working cord end upward with the other. As you pull, the wraps will compress together into a firm cylindrical shape. Pull steadily rather than jerking, which can distort the wraps.
The knot is done when the cylinder feels solid and the wraps are snug against each other. If the barrel looks a bit loose, you can add another gentle pull — the structure tightens nicely.
Step 7: Adjust and Secure
Slide the finished barrel knot along the filler cord to position it exactly where you want it. Barrel knots are mobile until they are locked in place by the knots around them.
To lock placement, tie a square knot directly below the barrel using the surrounding working cords. This secures the barrel knot and lets you continue building the rest of your pattern.
Getting Consistent Sizing Across a Row
When barrel knots appear in a row — across a wall hanging, for example — inconsistency becomes obvious. Here are the practices that make the biggest difference:
Always count wraps. Never eyeball. Even experienced makers count every wrap on every knot when precision matters.
Use the same cord for every barrel in a row. Switching between cord thicknesses mid-project will produce different-sized barrels even with identical wrap counts.
Check with your board's grid. After tying each barrel knot, use your macrame board grid as a size reference. If the knot spans two grid squares, every knot in the row should span two grid squares.
Keep the filler cord under consistent tension. If you let it droop for some knots and pull it tight for others, the wraps will compress differently and the knots will look different sizes.
Using Barrel Knots in Real Projects
Barrel knots work best as spacer accents between structural sections, not as the primary knotting technique. Here are the most effective ways to use them:
Between sections of square knots — A single barrel knot every 3-4cm along a column of square knots breaks the repetition and adds dimension without competing with the main pattern.
Along plant hanger cords — Barrel knots spaced evenly along the hanging cords of a plant hanger add texture and make the piece feel more finished. See the macrame plant hanger tutorial for a project where barrel knots fit naturally.
As fringe accents — Tie a small barrel knot at the end of each fringe strand instead of leaving raw ends. It adds polish and prevents fraying better than trimming alone.
In sampler pieces — If you are learning knots systematically, add barrel knots to your sampler alongside spiral knots and berry knots. The spiral knot macrame tutorial pairs well here — combining the two gives you a rich textural vocabulary.
Cord Choice for Barrel Knots
The cord you use significantly affects how barrel knots look and feel.
Single-Strand Macrame Cord (Regular Rolls) in 3mm or 4mm is the best choice for barrel knots. Single-strand cord wraps smoothly and the wraps stack cleanly because the surface is flat. The resulting barrel looks crisp and geometric.
3-ply cord works but has a subtly textured surface, which gives the wraps a slightly rougher, more organic look. That is not always wrong — for a rustic or nature-inspired project it can look intentional — but it makes it harder to achieve the clean cylinder shape that makes barrel knots so striking.
Very thin cord (1.5mm or 2mm) is harder to wrap evenly and the finished barrel knot can feel fragile. Save thin cord for decorative details where you are not relying on the knot's structure.
Common Barrel Knot Problems
Wraps keep slipping out of place. You probably are not threading the working cord back through the center of the loops. That threading step is what locks the wraps. Go back and thread the end through before tightening.
The barrel looks lumpy on one side. The working cord tension was inconsistent during wrapping — some wraps were pulled tighter than others. Try again with very deliberate, even pressure on every wrap.
The working cord is too short to thread through. You need at least 8-10cm of cord remaining after your last wrap to thread through. Shorten your wrap count or plan longer working cord lengths. As a general rule, the working cord for a four-wrap barrel knot should be at least 40cm to start.
The barrel knot slides around after I position it. It needs to be locked by surrounding knots. Tie a square knot directly below the barrel to anchor it. Barrel knots are not self-locking the way square knots are.
What's Next
Barrel knots are a natural stepping stone toward more advanced textural work. Once you are comfortable with them, try combining barrel knots with the techniques in the gathering knot macrame tutorial for projects that use both spacer and cinching details. For a complete overview of which knots build on each other, the 5 macrame knots every beginner should learn guide is a useful reference to keep open while you practice.
