Kora/Sedge Grass Mat Weaving of Kerala


Kora grass or Sedge grass yielding natural fibres have been in use since decades in Kerala to produce array of products. Extremely delicate, the mats made with kora / sedge grass are highly prized and valued; Kora grass grows abundantly along the banks of the rivers and in marshy areas. The process of creating the mat is complex and painstaking. In its original form the grass is green in colour and normally grows to a height of 3-4 feet. The grass for the mats is cut very finely while it is still green. The grass is collected in the months of September/ October and February/March. The tools used are basic and include Knife, Machete, Wooden mallets, Floor loom, Thandu – bamboo rollers, Pegs, Shuttle, Scissors Wooden tripod Polishing stones and long hooded needle. The inside white pith (choi) of the stem is removed with a sharp-edged knife while the outer part of the stem is used for weaving. The counts of the mat depend on how many strips the grass is cut into; the greater the number of strips from each stem the higher the count. The strips of grass are then dried in the hot sun. They are, however, never exposed to humidity, as they tend to turn black with the exposure. When the dried grass strips turn a yellowish greenish colour they are boiled in a pot of water and then dried again. The dried grass is made up into bundles and then soaked in running water. These bundles are weighed down with stones at both ends; they are then made to float in running streams of clean water. The weight of the stone is so adjusted that the grass remains just below the surface of the water. The grass is normally kept under water for three days, but sometimes it is kept under water for up to seven days, ensuring a very fine count. This wetting causes the grass to swell up to three times its original size. It is then dried again in the sun. The weaving is done on a floor loom. The process is slow and follows a basket weave pattern. The weft (or the grass) covers the warp entirely and the pattern formed has an interesting striped effect of its own. Once the weavings is complete, the mat is dried in the sun for a short while. It is then finished with a polishing stone. Traditionally only two colours — red and black — were used on the mats. For dyeing the grass both natural and chemical dyes are used. The natural dye is taken from sappon or Brazil wood and is fixed with an alum mordant. With the introduction of chemical dyes a wide range of colours have been introduced into the mats. The warp on which the grass mats are woven was traditionally made of elephant aloe fibre. However, the weavers have now started using cotton or silk yarn as a substitute in the warp while weaving. The warp is made by the men while the weaving is done by the women. The designs on the mats are constantly evolving, changing from simple stripes to reproductions of monuments, animals, plants, and trees. Kora mats are extremely pliable and can be easily folded. The products produced include sleeping mats, prayer table mats, floor matting, door mats, window and wall mats, letter boxes, bags, runners and baskets. These products have a potential export market which still stays untapped. Other than kora grass, coconut husks and Palmyra leaves are some more traditional sources of naturally yielding fibres used to produce products.
The products are made in the areas where the raw material is easily accessible like Chittur and Malmapuza in Pallakad District; Kilimangalam in Thrissur district.
