The Gamosa ([ɡamʊsa]) or Gamusa is an article of significance for the indigenous people of Assam, India. It is generally a white rectangular piece of cloth with primarily a red border on three sides and red woven motifs on the fourth (in addition to red, other colors are also used). Although cotton yarn is the most common material for making/weaving gamosas, there are special occasion ones made from Pat silk. A 1,455.3 meter long Gamusa displayed in Delhi created world record as it became the world's longest hand woven piece of cloth.
