I recently saw this on Apartment Therapy and fell in love with the idea. DesignYourWall.com gives everyone the opportunity to design wallpaper perfect for your personalized space. Their designers can take any pattern, photograph, drawing, etc. you provide and turn it into custom wallpaper. Customers can also choose the type of wall covering (removable wallpaper, grasscloth, etc.). The images here are some of my favorites from their existing collection, just to get your creative juices flowing!
