Do you have a bunch of pictures and wall art just laying in a box, needing a place to hang them? if you have enough space in your living room, it's another great area to create a statement gallery wall. if you haven't already seen a theme, gallery walls are great for places where a lot of people gather, like the dining room!
The great thing about gallery walls is that you don't need the same exact picture frames. In fact, mix and matching different sizes and designs can really add to the charm. I prefer to just wing it and start with one picture at a time and hang them as I see fit.
