White on white for impact
Consider going for a stairway display of your favourite snaps. Hang the bottom photo at an average eye level near a lower step; hang the next frame so the bottom edge is about one third of the way up the first; follow this pattern with subsequent frames and space all the frames equally from each other.
Choose matching frames and either all colour or all black & white photos. Alternatively, group family photos tightly in an arrangement showcasing different generations. Or mix it up by displaying signs or other wall art along with photos.
