The angular sleeves are about two feet wide and 45 feet long. Just as wide as the sleeves, a little narrower. The width of sleeves is the same as that of raw edges, but the length is doubled or longer, about one meter, because some sleeves have to dance. Anyway, the sleeve width is cut in one unit, that is 1: 1, 1: 2 or 1: 3. It has been roughly measured before, but it is not special. For your reference.
