Understanding Krokbragd Part 1: The Basic Structure
Krokbragd has one of those wonderfully unpronounceable Scandinavian names that immediately sounds more complicated than it really is. The word krokbragd is Norwegian and is often translated as "hook pattern" or "crooked pattern," referring to the characteristic geometric motifs created by the technique. Originating in Norway, this traditional three-shaft weaving structure has been used for centuries to weave colourful rugs and coverlets.
I still remember the moment I discovered Krokbragd. It was through the work of Angie Parker, whose bold, colorful rugs completely changed the way I saw this traditional technique. Until then, I mostly associated Krokbragd with historical textiles. Her vibrant color palettes showed me that Krokbragd could be contemporary, playful, and full of life, and introduced many modern weavers—including me—to its creative possibilities. In fact, seeing one of her rugs inspired me to buy my very first four-shaft loom, simply because I wanted to learn how to weave Krokbragd myself.

And since then, it's one of those weaving structures I never seem to get tired of. I've been fascinated by it for more than ten years, and it still keeps surprising me. Looking at a finished piece, it's easy to assume that creating such intricate motifs must require complicated drafts or advanced weaving skills.
The reality is quite the opposite. At its heart, Krokbragd is built on a remarkably simple and repetitive structure—and that's precisely what makes it so beautiful. Once the underlying logic becomes visible, many patterns suddenly make sense, and designing your own motifs becomes far less intimidating.
Discovering the Logic Behind Krokbragd
Rather than starting with a finished pattern and handing you a draft to follow—as we often do in weaving—I would like to take a different approach.
In this two-part series, we'll first uncover the simple logic behind Krokbragd and learn to recognize the three building blocks that make every pattern possible. In the second article, we'll use that understanding to create motifs step by step and begin designing our own.
By observing how colors move through the three weaving sequences, you'll learn to read Krokbragd as a visual language rather than as a collection of patterns to memorize. My hope is that by the end, you'll approach this technique more freely because you truly understand its underlying principles.
The step-by-step exercises that follow are, in fact, exactly the same ones I use in my in-person classes.
But first, let's make sure we have the right setup. Otherwise, the whole experiment won't quite work.
Before Creating Patterns: The Basics
Before exploring patterns, let's briefly look at the structure itself. Krokbragd may create intricate designs, but its construction is surprisingly simple.
Krokbragd at a Glance
• Weft-faced structure (you shouldn't see the warp at all!)
• Three shafts
Threading: 1–2–3–2
Tie-up:
-
Treadle 1 = shafts 2 & 3 (threads on shaft 1 stay down)
-
Treadle 2 = shafts 1 & 3 (threads on shaft 2 stay down – this is the plain-weave pick)
-
Treadle 3 = shafts 1 & 2 (threads on shaft 3 stay down)
Treadling sequence: 1–2–3, repeated continuously.
These three picks create one complete row of pattern.
Although the sequence never changes, endless patterns emerge simply by changing the order of colors in the weft.
This is the magic of Krokbragd.
A note about treadling notation:
You may also encounter the treadling sequence written as 1+2, 1+3, 2+3 rather than 2+3, 1+3, 1+2, as used in this article. Both systems describe exactly the same structure. I chose the second notation because I like to think about the warp thread that remains down (and is therefore covered by the weft): with 2+3, the thread on shaft 1 stays down; with 1+3, it's the thread on shaft 2; and with 1+2, it's the thread on shaft 3. For me, this makes the sequence easier to visualize. But both notations are equally correct, so feel free to use whichever one makes the most sense to you
Yarn Choice
Because Krokbragd is a weft-faced structure, the warp should generally be much finer than the weft.
The warp is almost entirely hidden in the finished cloth, so its color is usually unimportant unless fringes remain visible. Far more important is strength. Krokbragd requires a firm beat, and the warp must be able to withstand considerable tension and abrasion—something like Cotton Seine Twine #6 works well.
The weft, on the other hand, creates both the pattern and the surface of the fabric. Slightly thicker yarns generally work best, especially if you want to weave rugs. Gist's Dwella Rug Wool is an excellent choice.
For learning Krokbragd, it is helpful to choose wefts that:
• are similar in thickness
• are relatively smooth
• are not strongly variegated
Highly textured, fuzzy, or uneven yarns can blur the motifs and make the structure more difficult to read.
The Secret of Good Krokbragd: Sett
If there is one aspect of Krokbragd that challenges most weavers, it is the sett.
Because Krokbragd is weft-faced, the warp must be spaced surprisingly widely. At the same time, the beat should be firm and substantial. Finding the right balance can be tricky, especially because the usual sett calculations often don't work very well for weft-faced techniques.
In fact, there is one solution:
Sample, sample, sample! It's worth the effort—once you've found the right combination, you can use it again and again.
Too much warp showing? Space the warp farther apart.
Does the weft pack in effortlessly, with very little resistance? Then the warp may be too widely spaced, and the fabric could become too flimsy.
A good Krokbragd fabric usually requires a rather vigorous beat. Unlike balanced weaves, this is not a structure where the weft gently falls into place. I normally work with a set of 2 threads/cm (4 epi) for rugs and 3 threads/cm (6 epi) for upholstery fabrics or cushions.
Understanding the Three-Step Sequence
Every Krokbragd pattern grows from one simple sequence:
Treadle 1 → Treadle 2 → Treadle 3 → repeat
Three picks create one complete row of pattern.
I find it helpful to think of these three picks as one single design unit. Every motif in Krokbragd is built by repeating and combining this unit in different ways, no matter how simple or complex it may appear.
One detail, however, is particularly important.
The threading follows a four-end repeat:
1 – 2 – 3 – 2
Notice that shaft 2 appears twice. This means that Step 2 is, in effect, connected to a Plain Weave pick and occupies more visual space than Steps 1 and 3.
As a result, the color woven on Step 2 usually appears stronger and more dominant than colors woven on Steps 1 and 3.
This small detail explains many of the visual effects we'll discover in the next exercises and it’s really the key to understand how Krokbragd patterns work.
Step-by-Step Exercises: Watching the Structure Appear
And now we can begin our little experiment.
As with any weaving exercise, I encourage you to actually follow these steps on your loom rather than simply reading about them. Krokbragd suddenly becomes much easier to understand when you can watch the colors appear and move in front of your eyes.
Step 1: Establish a Background
Begin by weaving several inches in a single background color. In my example below, I use orange for all three picks.
Step 2: Add a Contrasting Color on Pick 1
Now replace only Pick 1 with a contrasting color. In my case (pictured below), I use white, while Picks 2 and 3 remain orange. Weave at least an inch to allow the effect to become clearly visible.
A subtle vertical column begins to emerge.
If you look closely, you will notice a repeating rhythm: three orange warp ends followed by one white column.
Step 3: Move the Contrasting Color to Pick 2
Next, move the white pick to Pick 2. Picks 1 and 3 remain orange. Again, weave at least an inch.
A completely different type of column appears. This time the white columns occur much more frequently and therefore appear much stronger and more dominant. In fact, every second warp end is now white.
This happens because Pick 2 is the Plain Weave pick (remember the threading: 1-2-3-2 ?) Every other thread stays below and is covered by the weft, so the contrasting color occupies much more visual space than it did on Pick 1.
Also notice that these columns are shifted relative to the ones created in the previous step.
Step 4: Move the Contrasting Color to Pick 3
Finally, move the white pick to Pick 3. Picks 1 and 2 remain orange. Again, weave at least an inch and simply observe.
A subtle vertical column appears once more, much like the one created on Pick 1. However, it is shifted relative to the columns of pick 1.
Now compare all three samples side by side.
Suddenly, the entire structure becomes visible.
This is the moment when Krokbragd suddenly begins to make sense.
These three column positions are the building blocks of every Krokbragd pattern. Once you understand these three possibilities, you can read—and create—almost any Krokbragd motif.
Colors woven on Picks 1 and 3 create subtle columns that appear every fourth thread, each shifted relative to the other. Colors woven on Pick 2, however, appear every second thread and therefore have a much stronger visual presence.
That's it.
The seemingly complex world of Krokbragd patterns is built entirely from these three simple possibilities.
In part two, we'll begin combining individual columns of color to create simple motifs, and explore the possibility of adding a third color to the mix. Stay tuned!
