Hand-knotted rugs are admired for their intricate detail and time-honored knotting techniques. They are made on a loom where warp threads build a foundation, onto which craftsmen tie each thread that is used to create the design and texture of the rug. Hand-knotted rugs will vary in the density of knots per square inch, texture, clarity of design, and vivid colors associated with this timeless rug construction. Because of the craftsmanship and the inherent quality of hand-knotted rugs, no two rugs are exactly alike.
