I wanted to thank everyone for their input on our guest room curtain dilemma. We've decided to go in a totally different color direction, so the whole argument has become moot. We found a new comforter set for the bed, which is black and white.

It appears they make matching curtain panels, but I've yet to find them for sale anywhere. Not sure I would want that much of the print in the room anyway. I'm sure it won't be difficult to find something else we can agree on, a black panel with a white stripe or something. We'll see how it all looks when the comforter arrives early next week.
