Ilkahaid  - The Mongol dynasty that came to power in Iraq and Persia  in the later thirteenth century. No actual rugs of this period are known, but they are represented in various Islamic and Chinese paintings. 

Ingrain – A form of machine loomed, flatwoven, reversible carpet that became popular in the nineteenth century. Adapted from the initial production that began in Kidderminster, England, Ingrain carpets remained popular until pile carpets became more available and affordable in the later nineteenth century. Designs were generally made in bold, richly colored reciprocal geometric patterns. Their production largely disappeared after 1920. 

Irish - In Ireland and Scotland the Arts and Crafts Movement gradually came to focus on native Celtic traditions from the Middle Ages, and eventually elements from the Art Nouveau movement in the late nineteenth and twentieth centuries. Irish Arts and crafts carpets tended to exhibit a fascinating blend of Celtic and oriental carpet designs. The Donegal type tended especially to include Art Nouveau elements as well. 

Isfahan  - The production of Isfahan may go back to Safavid times in the seventeenth century when Isfahan was the capital of Persia, since many of the court quality carpets of this period that survive today have been attributed to Isfahan. Nineteenth and early twentieth century antique Isfahan rugs continued the style and consummate technical virtuosity of their classical forerunners, although often with a softer, more decorative palette.

Jufti knot  -  A pile technique using symmetrical or asymmetrical knots but utilizing these configurations around pairs of warps rather than single warps, making the pile less dense and quicker to produce.
