Sadu, linguistically signifies all that is woven in a horizontal manner. Traditionally, the Sadu weaving process involved wooden pieces that held together vertical ropes of the underlying material over which patterns were woven horizontally using a sharp object usually made from a deer's antlers/horns. The Sadu fabric was used for the Arabic tent (also known as Khaima) and was believed to help in providing a good shade during desert afternoons and also trap warmth in the tent for cold desert nights. Material is made from woven camel/goat hair with geometric patterns representing objects and meanings. Colours are often bright and bold using orange, blue, black and white. It is a technique that has been used in the Arabian peninsula for hundreds of years.
