Because I am posting a third time this evening. I got the duvet cover home and tested it poste haste. I himmed and hawed a bit (and emailed a pic to Mom), but ultimately decided to keep it. I washed it up and put it on the bed! My uncertainty was basically because the yellow seemed duller than it did in the store, but I still think it works and is a happy addition to my bedroom. I like the contrast of the yellow with the gray walls and black and white material.
Please Note: this pic (aside from the gratuitous placement of my new West Elm tray, purposely placed there after my earlier post) is NOT styled...hence the random pillow placement, wrinkly duvet cover, etc!)
