This particular approach in carpet production is the oldest and most technical. The explanation is in the title; a skilled weaver individually ties every knot by hand, thus creating a totally unique handmade carpet.
Each carpet is set up on an individual wooden loom which is sized to the specifications of the carpet dimension. Once the loom is set up, the vertical threads, known as the warp, are tied to the loom. Following, the horizontal threads are introduced, called the weft, and the foundations of the carpet have been put in place. The knots, commonly made of wool or silk, are then tied to the vertical warp threads by hand, and tightened by a comb-like tool. The production travels from bottom to top. An experiences weaver can tie one knot every 2 seconds. Consequently the length of time to produce a hand-knotted carpet depends on the size, intricacy of the pattern and density of knots.
There are two different approaches to ‘knotting’ however Silk Avenue uses the ‘Persian’ knot technique, meaning the knots are open to one side. This type of knot produces a less bulky appearance and benefits from a much tighter structure.
The value of a hand-knotted carpet is placed within the knot density. Silk Avenue’s Knots per sq/inch can range between 45 and 500.
In summary, 100knots per sq/inch is considered high quality, 200knots per sq/inch is considered remarkable and 500 sq/inch is an extremely rare piece and can take several years to produce depending on the size.
The knot density can drop below 100 to even 40 knots per sq/inch, however Silk Avenue does not want to reduce the quality below 100 Knots.
Hand knotted carpets are typically more costly than other methods, due to its lengthy process. However, the technique produces an extremely durable carpet that would withstand high traffic. The life-span of a hand-knotted carpet is considered higher than alternative methods, therefore can be argued as being the best value for money.
