Krokbragd Visualizer

Krokbragd (pronounced "croak-brahg") is a traditional Norwegian weaving technique whose name is often translated as "crooked path" or "crooked lines," a reference to the stepped and zig-zag motifs commonly found in the cloth. It is a weft-faced weave structure based on a three-shaft point twill, producing dense, durable textiles such as rugs, coverlets, cushions, and wall hangings.

Unlike balanced weaves, where both warp and weft are visible, krokbragd is designed so that the weft completely covers the warp. The colors and patterns you see come almost entirely from the weft yarns, while the warp serves primarily as the structural foundation of the cloth.

Traditional Three-Shaft Setup

Traditional single krokbragd uses a three-shaft point twill threading with the repeating sequence:

1 – 2 – 3 – 2

repeated across the width of the warp.

The traditional tie-up is:

Treadle 1 = shafts 2 + 3 
Treadle 2 = shafts 1 + 3 
Treadle 3 = shafts 1 + 2 

This means that with each pick, one shaft remains down (or up, depending on your loom action) while the other two are raised. The weft covers the warp threads on the shaft that remains down.

The treadling sequence remains constant:

1 – 2 – 3
1 – 2 – 3
1 – 2 – 3

This is repeated throughout the entire weaving. Patterns are created not by changing the treadling, but by changing the colors of the weft picks.

Three Picks Equal One Pattern Row

One of the most important concepts in krokbragd is that three weft picks combine to create a single visible pattern row. A sequence such as:

Red – Red – White

This is read as one pattern row, not three separate rows. The visualizer on this page condenses those three picks into the single row of pattern that appears in the finished cloth.

Choosing a Sett

Because krokbragd is a weft-faced weave, the warp must be spaced much farther apart than it would be for a balanced weave. If the sett is too close, the warp will show and the pattern will lose its characteristic appearance. If the sett is too open, the cloth can become loose and unstable. Sampling is strongly recommended.

A common rule of thumb used by many weavers is to begin at approximately half the sett you would normally use for plain weave with the same warp yarn and then sample from there. For example, if a yarn is typically woven in plain weave at 12 EPI, a good starting point for krokbragd might be around 6 EPI. However, the ideal sett depends heavily on the warp, weft, desired fabric density, and intended use, so sampling remains the most reliable approach.

About This Visualizer

This tool is designed to help visualize color sequences in traditional three-shaft krokbragd. Click on the grid to assign colors to the three sheds, then experiment with different combinations of color order. Because the treadling remains fixed, even small changes in color placement can produce dramatically different diamonds, zig-zags, bars, and stepped motifs.

The visualizer uses:

Threading: 1 – 2 – 3 – 2
Tie-up: Standard 3-shaft krokbragd
Treadling: 1 – 2 – 3

It then condenses every three picks into one visible pattern row, just as the cloth appears on the loom.
