Our 600 thread count 100% sateen cotton duvet cover and shams are woven using very fine long-staple durable cotton yarns, this allows us to weave a super-smooth sateen fabric that is softer, stronger, and more luxurious than ordinary cotton sheets and duvet covers. We finished the duvet cover and shams with the classic scallop stripe embroidery style, and the design will enliven any bedroom. This collection also comes with matching sheet/duvet sets that will complement any bed!
