Harry Potterish bedding?

I say ish because I don't want it to be emblazoned with the harry potter logo or the harry potter faces. Oh hey there :P so I have a new bedroom and The walls are tan (that's probably not going to change) and all that's really in there is a desk and my bazillion harry potter posters, so I wanted to have a Harry PotterISH bedspread, like the castle or the hogwarts colors or my house color (I'm a Hufflepuff(yellow and Black)) or like owls or letters but I'm not sure where to find this stuff so if you could kindly lead my clueless self to a good place to look with nice PotterISH bedspreads I might love you forever/ give you a million dollars/ pick you as best answer (probably the last one :P) So thank you for helping me! You're great!!!!
