Story Behind the Art Heriz rugs are Persian rugs from area of Heris, East Azerbaijan in northwest Iran. Distinguished by monumental floral designs and the impressive angular drawing, Heriz rugs enjoy enduring popularity for their versatility and excellent craftsmanship. Even as most Heriz tend to have strong medallion designs accented using rich color, allover Heriz are not uncommon. Where other Persian carpets utilize a curved form, Herizes apply series of angular twists and turns, imparting an emphatic geometry to the design. Bright vibrant colors and characteristic bold patterns make these rugs easy to identify. Woven using knots 30 to 80 per square inch, Heriz rugs do not seem to be tightly woven as their Persian counterparts like Tabriz but are durable and famed for their longevity.
