I'm a huge fan of dropping artwork or mirrors behind sofas or beds to completely change the look and feel of a room. These are the arrangements that I have recently found inspiring:

Cozy meets industrial. I love it!

The desaturated blue of the painting really ties this room together.

Gorgeous gold back splash.

Absolutely adore this mirror and what a great piece of
furniture!

I love this. My good friend Kati's dinning room was featured on
Design*Sponge
I'm a minimalist at heart...

I love these paintings because they are super
quirky and jump out at you.

This is
probably my most favorite arrangement: simply beautiful.
Don't have a window? Bring nature to you!
