Gallery Walls: Same Shape, Same Size

The easiest way to create a gallery wall is to use frames of the same shape and size. You really don't need much imagination, just make the perimeter a square or rectangle. The pictures are in straight lines within straight lines, and you get a very clean, stream-lined look. Though this is the easiest, it's not always the cheapest. I personally love this style, a)because I'm OCD and love straight lines, and b)because it makes a big impact when you need a big piece.
