Hand-knotted rugs, like the Oriental Borlu Antique Rug, are admired for their time-honored knotting techniques. Craftsmen tie each knot to create the design and texture of the rug. Hand-knotted rugs will vary in the density of knots per square inch, texture, design, and color. The artistry of timeless rug construction means that no two rugs will ever be exactly alike.
