The most beautiful spaces in your home come together from your heart. Decorate with what you love or has a special meaning to you. Think about the room or rooms that you would like to bring a new look to. First, shop your home, keep it simple, maybe taking a small lamp from one room and relocating it to the room you are redesigning. Repurpose a piece of furniture from one room used functionally one way and now use it for a different function, in another room. 
You may surprise yourself.... with your new space. 
Blessings with your refresh!
