Organic Cotton Duvet CoverOur pure white duvet covers are handcrafted from premium 500 thread count organic cotton which is delightfully crisp, soft against your skin and woven at such a high density that it will be just as luxurious in years to come as it is today. To help keep your duvet in place, we sew small ties into the corners of the cover, which can be fastened to any duvet with corner ties, like our Organic Wool Duvet. All of our bedding is certified by the Soil
