I had been looking for quite some time for a replacement duvet cover and this one seemed to have it all.  I washed it before using, and since it's 100% cotton, I washed in cold water, and then hung it up to dry before tossing in the drier on low for a quick refresh.  Did not shrink at all.  I love the 4 corner ties that help hold my down comforter in place, and the zipper closures on both the pillow covers and the comforter are great.  The muted green pattern is lovely!
