This 110" X 98" envelope will accommodate a king-size down comforter, giving it a little style and versatility--plus, it's easier to wash than the comforter! It's reversible: one side makes use of a unique fabric panel with wide borders, and the other side has a large central panel and narrower borders. It's all about measurements!
