It is a great idea if you have a stairway or long hallway. I have one whole wall of pictures of my family in my livingroom like this above the piano. Dream Home,For the Home,Home Sweet Home,There's No Place
I assume this photo was taken in a bathroom however you can use everything you see some of the things you see in any country house room. Pastel flowers in a wooden box, rustic wardrobe, vintage looking pillows with a blue stripes.
