It's quite a personal preference, whether or not you like the look of art on a ledge (shelf).
Personally, I love it; constantly pinning images of this design idea.
But for some reason, I'm having a hard time deciding if it's something I want to incorporate
into my own home. You might remember these pieces I've been collecting. It's time they found a home on the wall, shelf or not. So the question remains, how do you all feel about the look?
