Wool has been the traditional material for floor coverings for centuries, and for good reason. Each fibre has a natural crimp that makes it bounce back, an outer layer that sheds liquid for a moment before it soaks in, and a high moisture content that makes it harder to ignite than most synthetics. Those qualities explain why a well made wool piece can last decades. What varies is the way it is made, the quality of the yarn and how it is finished.
01What makes good wool
Longer fibres spin into a stronger, smoother yarn that sheds and pills less. Wool from breeds raised in cool, wet climates, including many British and New Zealand sheep, is often chosen for floor coverings because it is coarse enough to stand up to traffic. Finer, softer wools feel lovely in the hand but crush more easily underfoot. A slight sheen and a firm, springy feel are good signs.
02Hand knotted
Each knot is tied individually onto the warp threads, which makes this the slowest and most durable method. The pattern goes right through to the back, the pile is dense and the rug can be repaired and rewashed many times. Knot density, often given per square inch, is a rough guide to detail and effort. These are the most expensive and the ones handed down.
03Hand tufted
Yarn is punched through a canvas backing with a hand tool, then sheared and glued to a second backing. Tufting is far quicker than knotting, so prices are lower and designs can be bolder. The pile can be soft and thick. The trade off is a shorter life, often ten years or so with daily use, and a latex backing that should not get soaked.
04Flatweave and kilim
Woven on a loom without a pile, flatweaves are thin, light and often reversible. They suit dining rooms, where chairs need to slide, and hallways with doors that open over them. Kilims and Berber style weaves fall into this family. A good underlay is essential, as they slip more easily than thicker pieces.
05Machine made wool
Power loomed wool rugs are woven by machine in wool or a wool blend. They give the feel of wool at a lower price, with even, consistent designs. Check the wool content, since a blend with a high share of wool behaves much like pure wool, while a small percentage adds little.
06Colour and natural dyes
Wool takes dye deeply, which gives rich, even colour. Undyed wool in ivory, grey and brown hides everyday dirt surprisingly well and does not fade. Small colour variations, known as abrash, are normal in hand woven pieces and part of their character rather than a fault.
07Is wool hard wearing?
Yes, and it wears gracefully rather than looking flat or matted. Dense, low to medium pile in a tightly spun yarn is the toughest combination and suits busy living rooms and hallways. Long, loose shaggy pile is softer but shows traffic paths sooner.
08Why new wool sheds
Loose fibres left from manufacturing work their way out in the first weeks or months, especially on tufted pieces. It is normal and not a sign of poor quality. Vacuum gently and regularly with the suction head, without a rotating brush, and the shedding slows and stops.
09Cleaning and stains
Blot spills immediately from the outside in with a clean, white cloth and cold water. Avoid rubbing, hot water and strong detergents, which can spread the stain and felt the fibres. For a deep clean every year or two, a specialist rug cleaner is safer than a home carpet machine, which can leave too much water in the backing.
10Underlay for wool
A felt and rubber underlay protects the back, adds cushioning and stops the rug creeping on carpet or sliding on wood. It also lets air pass underneath, which helps it dry if it ever gets damp. Cut it 2 to 3 cm smaller than the rug on each side.
11Price and value
Hand knotted wool rugs cost the most up front but can outlast several cheaper ones. Hand tufted and machine made options give the look for less with a shorter life. Divide the price by the years you expect to use it, and the gap often narrows.
12Where wool works and where it does not
Living rooms, bedrooms, studies and hallways are ideal. Kitchens and bathrooms are less suitable because steady moisture and grease are hard on the fibre and slow to dry. Strong sun fades natural dyes over time, so turn the rug every few months in a bright room.
13Sizing
Use the same rules as any other material, with the front legs of the sofa on it in a living room, 50 to 60 cm showing either side of a bed, and 60 cm beyond the edge of a dining table. Common sizes in the UK run from 120 x 170 cm to 200 x 300 cm. Wool rugs we add will show the construction, wool content and full dimensions on each page.
