Designer tip: Curate a gallery that is genuinely, uniquely you. Start with your largest statement pieces, and work outward. Keep it asymmetrical for a collected look. Mix and match dimension and texture for visual interest, and add a pop of color or some unexpected flair. Create a layered look by placing art on floating shelves and hanging it above it as well. Add a pop of color or unexpected flair for a finishing touch. Voila!
Decorating hack: Use a roll of kraft paper on the floor, cut to the dimensions of the space you're working with. Layout your treasures on the paper first, and when you find the perfect arrangement, outline it with a bold marker. Tack the paper up on the wall with thumbtack or finishing nail to minimize damage, and go to work on hanging your gallery as outlined.
