“Bare walls with no accessories can leave a space feeling unfinished,” says Castagna. “Instead, a carefully curated gallery wall instantly adds personality and interest to a room. You can incorporate different frame sizes, orientations, colours, and textures, and different elements like photos, posters, and even vinyls to add some personality to your home. This wall decor style can also grow and evolve with you over time, making it an evergreen design choice.”
