Bamboo baskets were developed as a response to variety of needs, which were skillfully made by the local craftsmen in variety of forms - that were used for domestic, farming and fishing needs.Woven mats were used to make large trays. They were strengthened with stiff bamboo splits. They were used for fishing, drying, sorting and threshing grains. Fish basket usually had a wide mouth with narrow neck to prevent the fish from jumping out. To combat the rainy seasons - headgear and ceremonial rain shields were made. The traditional decorative jhappi is a rain shield that symbolizes the harvest festival. Many other articles of farming populations are made from bamboo (including bullock cart, grain storage bins, low stools, etc.). In Assam the craftsmen use simple tools like dao, bill hook knife, jigs, etc. to shape their products. Also they use bamboo moulds, while making the jhappi.
