Making carpets was very hard work in which collecting raw materials is restricted to a specific period within the year. The raw materials were dried, and based on the intended colours, different methods of drying were applied. For example, when dried in the shade, its colour changed to a beautiful light gold colour. If it were dried in direct sun light then it would have a silver colour, and if they wanted to have a dark colour for the carpets, the raw materials were put in a pool of water and covered by poplar leaves ( ).
