I think there's an owl on the wall below. Can you see him?!
Here's another 'wall'. I have a fascination with religious iconography and symbolism, so I love this wall.
And, some pretty flowers. A simple 'display of affection' for a particular subject or fascination is so easy to undertake with a bare wall, a collection of adored pics, and some time. You don't even have to frame them!
Ask yourself: 'What is it I have a fascination for?' Or, 'Do I have a collection of drawings/art/images I'd like to display?'
Which leads to: 'If I do have a collection of things I could display....... where could I display them?' Or, put more simply...'Have I got a bare wall?'
Because: Displaying a collection of things we feel an affinity with connects us to our home in a very personal and intimate way.
