Begin by decluttering and rearranging furniture to create a comfortable and functional space in your living room. Add some decorative accents that complement the existing decor, such as throw pillows, area rugs, and artwork. Consider painting an accent wall or installing wallpaper to add visual interest. Incorporate plants and greenery to bring life and freshness to the room, and use lighting strategically to create a warm and inviting atmosphere. Finally, keep the room clean and organised to create a welcoming and relaxing atmosphere.
