For many of us, the wall along the staircase provides the biggest (and tallest) swath of blank wall space in the entire house. What's normally only a functional space can be beautified by transforming it into a gallery to showcase art and photos. But if you think matchy-matchy frames and precise measurements are required to create a good looking gallery, think again.
Look closely at this staircase gallery and you'll see there is no homogeneity in the pieces hung on the wall: some are photos, some are artwork; some are big, others are small; some are matted, some aren't; some are in color, some are black and white. Really there are only two threads of commonality among all of the pieces hanging on this wall. One, they are a curated collection of the (presumed) homeowner. And second, each of the pieces, regardless of size or shape, is hung relatively equidistant from the other. This lets the photos and artwork breathe and it gives it an overall cohesive look which is pleasing to the eye.
