Matka is a heavy weight silk made from very  thick  yarns. The yarns are obtained from short ends of silk from Mulberry silkworms (Bombyx Mori) and spun by hand without removing the gum (sericin). As such, there are slubs and irregularities that give the fabric a unique character. It looks something like a tweed, but the fibers are all the same color. Matka is good for suits , jackets and sews easily.
