38 frames and 3 weeks later, our gallery wall is complete. Really, this project could all be done in a weekend but I dilly-dallied quite a bit. Between buying, painting, matting, and hanging the frames and selecting/editing/printing pictures for them, I wanted some down time. But I absolutely love how it turned out!
At first I thought I may want to add more to it but I kind of like the current size. If I was to expand at all, I think I would throw up some frames on the other side of the staircase.
