Headgear and footwear has traditionally been made of felt material in Nepal. The felt is either made completely of wool or of a combination of wool and cotton mixed in the required proportion.
Unspun wool or wool and cotton is spread evenly over a mat and then rolled lightly and pressed under the feet for felting. The felted piece is then milled, washed, and dried.
In order to achieve good-quality felting, certain standards are maintained. For instance, the felting needs to be done of clean, well-carded wool and cotton, free from dust and other fibres and foreign matter. The wool and cotton should be evenly spread so as to ensure a reasonably uniform thickness and stiffness in the end product.
