Swanskin was a coarse white cloth produced in Dorset in the 19th century and used for clothing for agricultural and seafaring work. The heavy cloth was manufactured in Sturminster Newton, Dorset. There are no known examples left in Dorset, according to the Sturminster Newton Heritage Trust. However, this pair of duck-hunting mitts made of swanskin turned up in Change Islands, Newfoundland, a place where people from Dorset had settled, and where swanskin was known and imported. Source.
