A nyandui is a semicircular cap of the Nenets of the Kanin Peninsula. The cap-nyandui is worn by teenage girls, ladies and young women.
The caps are sewn from two pieces of fur (pizhika) with short earflaps sewn on. Strips of cloth are inserted at some distance from each other along the seam going in a semicircle from one side to the other through the top. The traditional sequence of colours must be respected: red, yellow, blue or green (or shades of these colours).
Sawa' ne (literally "legs of a cap") - two long strips of kamus (skin from reindeer legs) decorated with mosaic patterns of white and dark fur with cloth inserts are sewn to the back of the cap. They are connected with each other by copper chains or beads. Sawa' ne are not tucked into the belt but hang freely over a panitsa going down below the waist.
