Awesome Fabric

On one of my Goodwill Outlet trips I found this king size duvet. We don't have a king size bed but I LOVE the fabric! I just have no idea what I am going to do with it. I thought about perhaps curtains for the oldest daughters closets. Her doors fall off all the time and are pretty much too much of a pain to replace/repair. Not sure how it would look with the pool blue color in there however. Any ideas? It's too gorgeous to get rid of!!
