I've always liked the look of pictures hung gallery style on a wall. Its a great way to use small pieces to cover a large wall. Our home has a mismatch selection of art due to both sides of our families having artists as well as art picked up on some of our travels. I pondered the idea of doing a gallery style wall behind our t.v. but in the end I decided to hang 2 Ikea Malm floating shelves side by side and create a gallery style shelf instead. In my opinion the less cohesive the collection the better! If any of you have gallery style walls, I would love to see pics!
