The craft is traditional to the Santhal tribe of West Bengal. Madhurkathi grass which is abundantly available in West Bengal such as in the 24 Pargana area is used in weaving traditional file folders & mats. Patterns are made by dying the grass in different colors and then weaving the same with cotton thread as either warp or weft. The strips of woven mat are joined together by stitching with cotton fabric, which forms the folds and gives the particular color to the file folder.
