There are many ways to add summer vibes to your home, and one of the easiest is to change the accessories and wallpaper. Wallpaper has become a popular way to decorate homes, especially those that have been empty for a while. Wallpaper is available in many designs and patterns. A bold floral wall mural can change a room completely, or you can add a botanical design to a hallway. Don’t be afraid to mix and match patterns. Designer Christine Westcott suggests using plain textured wallpaper on three walls and patterned wallpaper on the fourth.
