Carpets from the vast area of Khorasan use a knotting technique in which four or more rows of weft are passed for every six to seven rows of knot. This produces a grooved effect on the back of the carpet. The most common layouts are the central medallion, concentric medallions or full-field decoration with Herati or small flowers.
Made using the asymmetrical knot, Meshed rugs often employ round or elongated medallion design that is embellished with pendants and floral elements. Frequently, the field is adorned with swirling coils of the Islami motif (an arabesque motif of a stem twisted around itself in a spiral). The Jufti or false knot, in which the pile yarn is wrapped around four warp strands instead of two, originated in this area. Although this system has been used in modern times to speed up weaving process, it was first used to achieve particular effects of emphasis.
Baluch rugs can be identified by their softness an their dark ground colors of red, brown or blue which are lightened by the white, pale green and yellow designs. These rugs also use a shade of Aubergine purple. Baluch prayer rugs are distinguished by long, rigid niches with squared archers and typically include a tree of life against a camel-colored background.
