Wallpaper seems to have made a comeback. It is great as an accent wall or behind a bookshelf and can instantly add visual interest with texture, patterns and color. You can get reproductions of vintage prints from companies like Bradbury & Bradbury Wallpapers or unique original patterns like the ones put out by Grow House Grow. Anthropologie has an artful selection of wallpaper to browse. This year I sold several homes that had vintage wallpaper and I encouraged the buyers to preserve a wall of it whenever possible.
