Nubi is a method of sewing in order to put cotton, fur or mulberry paper between the outer fabric and the lining of cloth, or of broad stitching without putting anything between the outer fabric and lining to strengthen the cloth or to make it warmer. Nubijang refers to this skill or to an artisan with such a skill. The method became a common practice following the introduction of cotton growing. Some monks wore the same robe for tens of years, repairing it with this method. Nubi techniques developed to a point where even ordinary people came to adopt them.
Among the things needed for the work of nubi are thread that matches as closely as possible that used on the clothes or bedding, needles, scissors, a heating iron, a push stick, a measuring stick, and a thimble. Regular straight lines are chiefly used for the nubi work on clothes or bedding, but a mixture of straight and curved lines are also used to make a pattern when working on wrapping cloth or pouches.
The country’s traditional manual nubi sewing is said to be an artwork similar to embroidery, but it is gradually disappearing, as the work takes time and does not bring much economic benefit.
