Bhavani Jamakkalam refers to blankets and carpets manufactured in Bhavani in Erode district, Tamil Nadu. It has been recognized as a Geographical indication by the Government of India in 2005-06.
In the late nineteenth century, competition from British made textiles led Indian weavers to invent new types of garments. In Bhavani, a community of weavers called Jangamars weaved a type of blanket using colored coarse threads called Jamakkalam. The popularity of the product led to the production of jamakkalams by other weavers replacing the production of traditional sarees and other cloths.
