Thrum mitts are a very unique and servicable mitt. They have knitted in "thrums" (small pieces of rovings), which line the inside of your mitt. The Thrum Mitt is hails from the Maritimes where the fishermen used these mitts to keep warm - when the roving lining felts (with heat and moisture), it creates a knitted in lining, helping to keep out moisture and wind. All of these mitts are hand knit of course and each one is unique. They are extremely popular.
