I need an AWESOME, decorative, fun blanket for my bed, where can I find such an object?

I have a very bland room (all white and off white) and plan on making it my own by adding personal touches —starting with a bedspread. Last time I did this I found a great one at Urban Outfitters, but no luck this time. Do any of you have any suggestions? I plan on having a duvet which can be plain but I want something fun spread on top (could be a tapestry, large throw blanket, etc…). Suggestions anyone?
