The colour of tussar depends on the climate and the diet of the silkworms. Natural tussar can come in off-white, cream, honey, beige, tan, or golden colours. Some common motifs on tussar silk saris include flowers, fishes, tortoises, and geometric patterns. However, the curvilinear and nature-inspired designs of Odisha are seen prominently on this fabric. Tussar is used as a base for a variety of weaves. The Assamese variant, geecha, is sometimes woven with a slightly stiffer unwashed yarn for a unique texture. Tussar from Gopalpur in Odisha attributes its special sheen to the use of Brahmani River water in the making process. The Keonjhar and Mayurbhanj districts of Bihar are also rich in tussar production.
