I have 1 dark olive green duvet cover. It fits my king size duvet and I use it on a queen bed. It also comes with two shams. It's like a sateen type fabric. The photo of the colour doesn't do it justice at all. I couldn't get a decent shot of the colour.
The other duvet cover is Ken Done art work (white background with colourful birds) and it comes with two pillow cases.
I work in town M - F and can always bring them with me if you want to see them.
