5. Rearrange Artwork and Accessories
This idea involves no cost at all! Take everything off of your walls and shelves. Then with fresh eyes, recreate your room by placing the art and decorative objects in different spots.
For a focal point, group wall art (framed or unframed) together in a gallery-style arrangement over a console table, fireplace, or sofa. On shelves, organize books together based on color. Sprinkle a collection throughout bookshelves, instead of clumped together in one row.
