My favorite gallery wall in our house is in our dining space. We've dubbed it the "places we've lived and been" wall because we like to collect prints, photographs, and art from all the locales we've been blessed to travel and all the states we've lived in.
Our gallery wall doesn't include every place we've traveled because we have art from some places in other parts of our home, but it does show a good representation of some of our favorite cities, states, and/or countries we've been to so far.
We've kept it simple with all black frames, which keeps it cohesive despite all the colors, shapes, and mediums. It's almost starting to resemble a heart, huh?
Do you have a gallery wall in your home? What have you chosen to feature?
