Sambalpuri sarees are known for their incorporation of traditional motifs like shankha (shell), chakra (wheel), phula (flower), all of which have deep symbolism, but the highpoint of these sarees is the traditional craftsmanship of the 'Bandhakala', the Tie-dye art reflected in their intricate weaves, also known as Sambalpuri "Ikkat". In this technique, the threads are first tie-dyed and later woven into a fabric, with the entire process taking many weeks. These Sambalpuri sarees first became popular outside the state when the late Prime Minister Indira Gandhi started wearing them. In the 1980s and 1990s they became popular across India.
