Persian rugs from the Kurdish town of Bidjar in northwestern Iran, known as the "Iron Rugs of Persia" due to their exceptional durability and dense weave. Feature intricate floral and geometric designs with a distinctive tight weave that makes them extremely sturdy and long-lasting.
A sampler rug: a small piece woven not for the floor but as a three-dimensional pattern reference, showing sections of borders, medallions, and field designs that a workshop could combine into full-size carpets. Essentially a weaver's catalogue in carpet form, vagirehs let master designs travel between villages without paper. Antique examples, particularly from Bidjar, are now sought-after collector's items in their own right.
