The vast province of Khorasan is one the most important weaving centres in Iran. The art of carpet weaving in this province dates back to the Sassanian period (241-641 a.d.). When Shah-Rokh Mirza (Timurid Dynasty), was in power (1405-1447), Harat the capital of this dynasty, which is now is Afghanistan was one of the most important weaving centres in Iran.
The famous design of "Harati" that is very popular among the Persian weavers, is attributed to the designers of this city.
Like other weaving centres in Iran, its progress is related to the period of the Safavid dynasty, but the real boom in the carpet industry began when the merchants of Tabriz installed many looms in this region for exportation purposes.
In this province, carpets are woven both with Persia (Senneh) and Turkish (Ghiordes) knots, (majority in the Persian knot).
The designs that are mostly used are Sh Botteh and Har
The dyers utilise natural colours such as mauve red, dark blue and some other classic dyes.
