I've never stopped loving wallpaper, even after having to scrape and peel off many layers of old paper in 2 of our homes. I recently made-over our office/family room, and thought that it would be a great room to use a bold paper. It's a little bit of a departure from the décor in the rest of the house, but I love the fun vibe that it brings. I loved adding vintage, cottagey pieces next to a pattern that could have taken the room in a modern direction.
