Hand-knotting is a traditional technique used to create rugs and textiles by tying individual knots to form patterns and designs. Each knot is carefully tied by hand, allowing for intricate details and unique craftsmanship. This method is often used in the production of Oriental rugs and Persian carpets, where artisans employ various knotting styles to achieve different textures and appearances. The process of hand-knotting can be time-consuming, as it requires skill and precision. Artisans typically work on a loom, using materials like wool, silk, or cotton. The quality of a hand-knotted piece is often determined by the number of knots per square inch, with more knots indicating a finer, more durable product.
