In Tamil Nadu, kora or sedge grass grows wild on river banks beside ponds and water channels. Four generations ago weavers came from Sirkali, Thekkal and Chidambaram and settled in Odiampet, Villanur. The Kumbakkam Lake provides the necessary water for growing and processing the grass stalks. Harvested grass is split into two manually or by a splitting machine and dried in the sun. Mostly women practice this craft.The Labbai and Rowther peoples who were originally Islamic preachers and took to mat weaving based in Pattamadai are known for their weaving of fine kora grass mats which are made from finely split korai. The kora grass is processed in the water of Tampraparani which helps to soften the kora grass and make it both pliable and have finer splits, the fine splitting of the grass have made the mats of Pattamadai famous. Whereas, mats produced by other districts are woven with coarser splits. The weaving requires both craftsmanship and creativity. Pattu paai / Pattamadai Pai (mat) is a beautifully crafted floor mat, which is ideally gifted to the bride by her parents. Traditionally at a Brahmin wedding these mats are gifted to the bride (and are specially woven with the names of both Bride and Groom).
