I feel like 99% of walls can go from boring to charming by simply adding floating shelves. I'm always hesitant to set up floating shelves because of the holes in the walls, but I never regret it once they're up. They have beautifully elevated this little space.
I found these old window panels at a local antique shop! They are painted dark green on the other side, and actually quite damaged - nails sticking out, wood chips flaking off, etc... but all these things just add to the charm, right? I chose to expose the natural wood because it ties in the variety of woods we have in the kitchen and living room.
I have linked these shelves in the button above. Happy decorating!
