Bihar has a tradition of carpet-weaving since the Buddhist and Mauryan era. The carpet industry found royal patronage about 300 ago, during the Mughal period and it is since then that pile carpets started being made here. Carpets with traditional Indo-Persian designs and floral and geometric motifs are made here. Cotton dhurries are also made made. Due to the hot Indian climate they are used widely. They can be patterned in a single colour or they can be multicoloured. The patterns include simple lines, geometric designs, and symmetric motifs.
