The most common headgear of the Monpas is the hat made of yak’s felt. It is called ngama-shom or tzithpa-shom in tsoksum area, nga-sha in Mago-Thingbu and dhueja in Zemithang area. A required quantity of yak’s felt is placed in a basin to which is added hot water containing crepe apple juice. The yak’s felt is then kneaded for about an hour. It is then moulded with hands giving it a desired shape of hat. The tapering point is twisted out from the material of the body.
