Like others have suggested, I try to make use of my wall space first and foremost to keep surfaces clear. (I can only think of three tabletop photos in the whole house, actually.) I try to keep like items together to give it some cohesion. I’ve also implemented limitations on what I’ll frame to try to stop it from getting out of control. For example, my pets each get one nice photo of themselves in an 8x10 and one collage frame that holds another 10-12 of my favorites taken over the course of their lives. The pictures of the pets who are no longer with us are hanging in a spare room and our current pets will hang, once I get them done, in the hallway of family photos. Pets on one side, kids on the other. Each kid has a section of wall saved for their photos. By the time they’re adults, each section will have a 16x20 frame of their newborn photos surrounded by 18 10x10s — one favorite picture from each year. We have about 50 of our favorite travel photos framed in thin 8x10 frames clustered over our living room couch, and as more come along in the future they’ll have to be swapped out. A collection of wedding photos is on another shorter wall in the living room. I have a spot for kids’ artwork to hang in “storage frames” so it can be rotated. At Christmas, we have a tree decorated with framed Christmas photos. Everything else is relegated to photo albums or Facebook memories.
