Kosa or Tussar silk sarees come from Chattisgarh (Originally Chattisgarh was a part of Madhya Pradesh).
Kosa silk is known for its comfort and popular in other countries. Bilaspur,Raigarh,champa of chattisgarh are known for kosa silk and its produce by Dewangan community.
The silk is valued for its texture which lends itself beautifully to printing and painting and is therefore increasingly used in designer boutiques to craft some of the most innovative motifs ever. The fabric is an ode to the imagination of the weavers, as each of the typical Fera and Jaala weave patterns seems to narrate its own special tale, with inspiration drawn from sources ranging from nature to mythological stories.
Kosa silk is drawn from cocoons grown specially on Arjun, Saja or Sal trees and are obtained naturally in shades of cream, honey, beige, yellow and ash. However, these natural hues are tastefully dyed using dyes made from vegetables, fruits, flowers, pollen, lac and other natural substances. The Kosa cloth is available in a range of colours and patterns that are block-printed or embroidered.
Particularly famous are the kantha-embroidered Kosa wear which chiefly involve floral and abstract designs made of small running stitches in a medley of colours ranging from the riotous to the more sober pastel shades.
