Krościenko, with its hamlet of Kąty, where the fulling mill comes from, and the surrounding villages, is a region inhabited by the Pieniny Gorals, while the Pieniny Mountains and the neighbouring Gorce Mountains to the north are traditional pastoral areas. Wool was spun and woven in village workshops, and the finished cloth was felted in fulling mills. Felting consists of hitting cloth with wooden hammers moved by water power and exposing it to cold and hot water. As a result, the fabric shrinks and thickens, forming compact cloth. This particular fulling mill was used to sew items of village clothing such as breeches and vests.
The ‘Na Kątach’ fulling mill was built by Jakub Dyda in 1928–29 and operated until 1968. It functioned almost continuously in April and May, when there was plenty of water, and in the summer after prolonged rainfall. The building housed a two-chambered (in later years a single-chambered) room, in which cloth was beaten by hammers moved by a shaft turned by the mill’s wheel. A stone hearth with a boiler for heating water, which was fed into the felting chamber via a wooden trough, is an important part of a fulling mill’s equipment. Cold water was supplied to the second chamber. The fulling mill was moved to the Sądecki Ethnographic Park in the early 1970s. The water wheel, the water supply system and the felting log had not survived, so these elements had to be reconstructed, as did the furnace with the boiler. The interior design of the fulling mill is completed by woollen fabric for fulling and finished cloth. A mill with mechanical querns, located in the side annexe, was also reconstructed.
