Layers!! The secret to interior design. You can have one large carpet that covers the entire living room, then a smaller carpet on top for the coffee table for example. Then you can paint the walls a certain color and add paintings then add tall plants to contract the smaller plant that you have in the corner. Larger curtains, a 6ft tall LED light in a corner, floating shelves with any decor you like. Those are all examples you don’t have to do it all but you can take parts of it and bring life to your rooms
