Using mirrors strategically doubles visual space by reflecting light and views. Place a large mirror opposite a window to maximize natural light or near art to amplify style impact. Mirrors create an illusion of depth, making cramped rooms feel open and airy. Opt for wall-mounted or leaning mirrors that don’t clutter floors. Group smaller mirrors in a gallery style for artistic flair that also expands the room’s feel. This simple DIY home decor hack boosts brightness and comfort while keeping budgets low.
