This wallpaper below is graham and brown. I actually have this wallpaper in my powder room on our main level. It's a mint green with metallic silver medallions. When I walk in, it makes me happy. :)
This one is by Todays Interiors. Love.
same print in another color
Here is the morrocan one again in a turqoise.
This one is by Amy Butler and I think it's really elegant looking. Great in a dining room.
So, the best site to find wallpaper is here. In the "find it fast" type in what you are looking for. Contemporary, Blue, Brown, etc. Happy wallpaper hunting.
