The carpet ("kilim") industry remains dominant in the town. Carpets have been crafted according to traditional designs, but in recent years it is up to the customers to decide the pattern of the carpet they have ordered. The production of a single carpet takes about 50 days; primarily women engage in carpet weaving. Work is entirely manual and all used materials are natural; the primary material is wool, coloured using plant or mineral dyes. The local carpets have been prized at exhibitions in London, Paris, Liège and Brussels. The kilim making of Chiprovtsi was inscribed on the Intangible Cultural Heritage list of UNESCO in 2014.
