Lanna Kingdom or the upper northern part of Thailand is the area from which many types of local fabric are originated because there are many ethic people in this area. Each ethic group can weave fabric for different purposes and with certain unique features. Thus, local woven fabric of Lanna Kingdom has diversified styles, techniques and motifs in accordance with the origins and ethnic groups. This manifests the abilities, creativity and wisdom of each ethnic group. In the past almost all communities wove fabric because clothing is an important factor of a human life. Thus, Lanna women had to know how to weave fabric. Fabric woven by Lanna people can be categorized into 2 categories. The first category is the fabric for daily use. Fabric of this type is not delicate or beautiful. Examples of such fabric are wrap-around skirts that the locals wear while working or staying at home. Such fabric is generally woven from cotton in plain and simple colours or with simple motifs. The fabric that is used for making clothes worn in daily life is roughly woven cotton that is durable, and dyed with colour from natural materials such as indigo plants that are used for dyeing ‘Mo Hom’ fabric. Apart from clothing, fabric of this type is also used for making scarves, blankets and bags. Even though most fabric of this type has simple styles, some areas might weave it to have motifs and beautiful colours. The fabric in the other category is the one woven to be used in special occasions such as in important religious rites, festivals and ceremonies, which require attendants to wear fabric that is delicately beautiful. This is because not only does the fabric of this type shows the weaver’s skills that contests with others’ but it also has to concur with beliefs and traditions of people of each ethnic. In such special occasions, women, as weaving specialists, will dress themselves up with fine fabric with beautiful motifs and colours in order to show their skills. Apart from weaving the fabric for daily use, Lanna people use fabric and threads for making things that are related to their local religion, beliefs and traditions, such as to use threads and flag for making vertical flags to be used in rites and ceremonies.
