These duvet covers fit the duvets perfectly and are beautifully made. They are incredibly soft and are not flimsy, nor heavy. There is a covered zipper on the side of the cover, which is a brilliant improvement, and this makes inserting the duvet into the all cotton cover so much easier than putting it into an opening at the bottom. We are so impressed with the quality and fit, and very happy that we purchased these duvet covers. They look and feel elegant. Shipping took only a few days from Canada and they were well packed and protected. Laura was very helpful. An excellent purchase from an excellent company. Thank you!
