Staircase photo gallery project

I always have a project or two brewing around here. Never mind that having two munchkins pretty much hinders any chance of getting my projects done in a timely manner (or ever) ... I can still hope and dream big.

Right now I want to create a photo gallery up our staircase. A lot of open wall space is annoying to me and we have some great photos and art that need displaying.

I found some great inspiration online -- but it's obvious that these took a lot of time, effort, and an eye for detail (all of which I don't possess).
