A rug measuring 200 by 300 centimeters contains, on average, between 250,000 and 400,000 individual knots. Each knot is placed by hand around two warp threads, cut, and beaten in. That figure makes the timeline understandable, but it does not yet explain *how* a rug is created. What precedes those knots, how the warp is tensioned, how a pattern without a drawing is executed: that is the craftsmanship contained in every square centimeter.
This article covers the entire process. Not from store to living room, but from raw fleece to finished rug.
The loom: horizontal or vertical
Everything begins at the loom, in Arabic noul mentioned. In the Atlas Mountains, two types are predominantly used: the horizontal ground loom and the vertical standing loom.
It horizontal ground rope is het oudste en eenvoudigste. Twee houten balken worden op de vloer gespannen, de weefster zit er gehurkt of zittend achter. Dit type is draagbaar, ideaal voor nomadische weefsters die het opvouwen en meenemen. De kledbreedte is beperkt tot wat de armen comfortabel kunnen bereiken, zelden meer dan anderhalve meter. Veel kleinere Beni Ouarain-kleden en traditionele Azilal-stukken ontstaan nog steeds op dit type getouw.
It vertical standing loom is more stable and suitable for larger formats. The warp, the lengthwise threads that form the skeleton of the rug, is stretched vertically between two horizontal beams. The weaver works from the bottom up, row by row. In cooperatives in villages like Ait Benhaddou or in workshops around Marrakech, a second weaver sometimes sits next to the first; both work simultaneously on the same width. This doubles the pace, but requires both women to maintain exactly the same knotting rhythm. Otherwise, the pattern becomes crooked.
What both types have in common: the shear stress determines the quality of the finished product. Warp that is too loose results in a limp structure that starts to ripple after years of use. Too tight, and the knots get stuck and cannot be properly set. Experienced weavers feel the tension with their fingers and correct it during the cast-on.
The knotting process: Ghiordes versus Senneh, and what knot density really means
There are two dominant knotting techniques in the hand-knotted garment industry. The most widely used in Morocco is the Ghiordes knot, also known as the Turkish knot or symmetrical knot. A wool thread is wrapped around two adjacent warp threads, with both ends facing forward. The knot completely encloses both threads. The result is a compact, robust pile that is highly resistant to wear.
The Senneh knot (also known as the Persian knot) works asymmetrically: the wool thread goes around one warp thread and along the other. This results in a finer pile and makes higher knot densities technically feasible, but requires more precision per knot. You also encounter this technique in finer Moroccan rugs, particularly from urban workshops, although the Ghiordes is the norm in the Berber regions.
After each row of knots, one or more weft threads (horizontal threads of wool or cotton) are woven through the warp. This locks the knot row and gives the rug its stability. Then the weaver beats the row with a comb or metal rod: she presses the knots and weft firmly downwards. This beating, in the jargon to beat, partly determines the density of the final product.
Knot density is expressed in knots per square centimeter. A simple Berber rug in the Beni Ouarain style has 4 to 6 knots per cm², which gives it that characteristic soft pile. A finer piece with more pattern and color changes reaches 8 to 16. The higher the density, the longer a row takes and the more wool goes into the rug per surface area. Density is not an end in itself, but it is the objective measure by which labor intensity can be measured.
| Characteristic | Machine-operated | Hand-knotted |
|---|---|---|
| Buttons | Even, identical | Slightly irregular, evidence of craftsmanship |
| Material | Polyester or acrylic | 100% Atlas wool, including natural lanolin |
| Fringes | Sewn or glued afterwards | Extension of the chain, part of the tissue |
| Lifespan | 5-10 years | Decades to generations |
| Cartridge | Identical reproducibility, pixel-precise | Unique per rug, executed from memory |
| Back | Latex or jute backing, no visible knots | Individual knots visible, structure mirrors front |
| Weight | Light, thin construction | Heavy due to wool content and layer-on-layer construction |

The weavers: a craft passed down orally
In most mountain villages of the Middle and High Atlas, women weave. Not as an exception, but as a structural practice dating back to long before the arrival of paper, textbooks, or design schools. Amazigh women, The Berbers, who have lived in this area for millennia, pass on their patterns through direct transmission: mother to daughter, older sister to younger, experienced weaver to apprentice.
There is no technical drawing on paper that is translated to the loom. The pattern is in the head. Weavers think in knot sequences: so many knots of this color, then a transition, then a repeat. Whoever knows a geometric pattern knows its structure: the axis of symmetry, the repeat module, the rhythm. That is the knowledge that is passed on.
What this means in practice: two women who know the same basic pattern weave two different rugs. The choice of color, the proportions, the small deviations that occur when an eye briefly misjudges a distance—these are the variables that make each piece unique. No mistake, no flaw: these are the characteristics of an object made by a human, not by a machine that performs every cycle identically. You can read more about why no two rugs are identical in a separate article.
The role of cooperatives, such as the partnerships we visit in the Atlas Mountains, is to organize work and sourcing without undermining the individual autonomy of the weaver. A cooperative offers shared access to wool, dyes, and sometimes distribution channels. The weaver works at home or in a communal space, at her own pace, with her own hands.
Timeline: from shorn fleece to finished rug
The weaving process does not begin at the loom. It begins with the wool. Atlas sheep are shorn in the spring; the fleece (the membraneIn addition to wool fibers, wool also contains lanolin, the natural fat that gives wool resistance to dirt and moisture. After shearing, the wool is washed, sorted by quality, and spun into thread by hand or mechanically. In many traditional contexts, the same community does this themselves; in larger-scale production, spun wool is purchased from regional spinning mills.
Then there is the painting. Historically, exclusively plant-based dyes Used: henna for red and orange, indigo for blue, pomegranate peel for yellow and ochre, walnut shell for brown. These dyes bind to the wool fiber via a mordant (a metal salt such as alum) that fixes the dye. Synthetic dyes are cheaper and more consistent, and are commonplace in much modern production. Traditional vegetable dyeing is recognizable by the somewhat muted, deep tones that do not clash but blend into one another.
After wool preparation and dyeing, the weaving itself begins. For a rug measuring 200 by 300 centimeters, with a knot density of 6 knots per cm², that amounts to approximately 360,000 knots. An experienced weaver lays an average of 800 to 1,200 knots per hour. With a 6-hour workday, that is a maximum of 7,200 knots per day. This means 50 to 75 working days of pure knotting, excluding setting up, beating, weft weaving, and finishing. With a labor-intensive pattern involving many color changes, the pace slows down considerably.
In practice, a rug of this size takes 2 to 4 months, depending on the weaver, the pattern, and whether work is alternated on other pieces. Finer rugs with a higher knot density can take longer. Simple, coarse Beni Ouarain style progresses faster due to the lower density per cm².
Na het weven wordt de pool gelijkgeschoren: de uitstekende wolpunten worden bijgeknipt tot een egale hoogte. De franjes, die aan voor- en achterkant uitsteken, zijn de uiteindes van de scheringdraden: niet genaaid of gelijmd, maar een organisch onderdeel van de constructie. Tot slot wordt het kleed gewassen en gestrekt, en vaak in de zon gedroogd om de vezels te zetten.
How to recognize the weaving process from the back
Turn a rug over. The back tells more about the production method than the front ever can.
With a hand-knotted rug, you see the individual nodes: small bundles of wool, each individually wrapped around two warp threads. They are visible in rows, with the weft threads in between. The rows are not perfectly straight: they run slightly wavy, and the knots show minimal variations. This is normal and expected. A precisely identical, smooth reverse side indicates machine production.
Also pay attention to the warp wires yourself. In handmade items, they run continuously from top to bottom through the entire rug; the fringes are their ends. In machine production or cheaper handmade imitations, fringes are sometimes sewn or glued separately to a jute or latex backing. Feel the transition between the fringe and the rug edge: is there a seam, or does the thread run seamlessly?
The pattern reflection is a third indicator. In a hand-knotted rug, the back mirrors the pattern of the front, less sharply but recognizably. The color blocks that you see as a pattern on the front are visible on the back as knot groups of the same color. In a machine-made rug using printing technology, the back is blank or illegible.
Finally: the weight. A hand-knotted rug measuring 200 by 300 cm easily weighs 10 to 15 kilograms due to the pure wool content. If you lift a rug of that size and it feels light, there is little wool in the construction, or it is thinner than the pile suggests.

Frequently Asked Questions
1. What is the difference between a Turkish knot and a Persian knot?
The Turkish knot (also known as the Ghiordes or symmetrical knot) completely encloses two warp threads: the wool thread passes over both threads and both ends emerge. The Persian or Senneh knot is asymmetrical: it goes around one warp thread and along the other. The Ghiordes knot is more robust and faster to tie, while the Senneh knot allows for higher knot densities and finer patterns. In the Berber weaving tradition of the Atlas Mountains, the Ghiordes knot is the standard.
2. How many knots does a high-quality hand-knotted Berber rug have per cm²?
A high-quality hand-knotted Berber rug typically has 6 to 12 knots per square centimeter. Coarse styles such as Beni Ouarain deliberately have a lower density: 4 to 6 knots per cm², for a soft, fluffy pile. Finer rugs with geometric patterns reach 8 to 16 knots per cm². The density partly determines the weight, wear resistance, and production time: the higher the density, the more hours per surface area.
3. How long does it take to make a 200×300 cm Berber rug?
With a standard knot density of 6 knots per cm², a 200 by 300 cm rug contains approximately 360,000 knots. An experienced weaver lays 800 to 1,200 knots per hour. With a 6-hour workday, this means 50 to 75 working days of pure knotting, excluding wool preparation, setting up the loom, warping, and finishing. In practice, a rug of this size takes 2 to 4 months. With a finer pattern or higher knot density, this can increase to 6 months or more.
