Inspired by soft, woollen blankets: the Tartan Tweed duvet cover brings warmth to your bedroom. Not only thanks to the diamond pattern on a grey-blue, white and anthracite woollen background, but also because the cover is made from 100% cotton flannel. Perfect for cold nights. The back of the duvet cover is grey-blue. The duvet cover is made of 100% cotton flanel. The cover can be washed below 60 degrees, can be tumble-dried and ironed.
