Bright Grey Plain Cotton Matka Fabric. Matka is an Indian term for rough handloom silk fabric made from very thick yarns spun out of the pierced cocoon in the weft and organzine in the warp. The yarns are obtained from short ends of silk from Mulberry silkworms and spun by hand without removing the gum. As such, there are slubs and irregularities that give the fabric a unique character. It looks something like tweed, but the fibers are all the same color.
