The gallery wall. It's kind of the ultimate signifier of a home owner's style. A way of saying "I live here, this is so me". We see them all the time on pinterest. But what about in your friends' homes? Maybe a little harder to come by. Because, for one thing, an art collection takes time (and some money) to curate. And two, a good gallery wall is friggin' hard to pull off. But worth it when you do.
Gallery walls add dimension and texture to a room. They allow you to showcase your style through many pieces as opposed to just one. Just be sure that what you're collecting and showcasing is representative of you. And have fun with it. Seriously. The stuffy art collections always come off as, well, stuffy.
