Decorating a wall with an electric fireplace involves several key steps. First, choose the right electric fireplace that suits your style and room size. Next, create a feature wall to make the fireplace the focal point, using materials like stone or wood for added texture. Incorporate built-in shelving around the fireplace to display books, decor, and other items. Enhance the ambiance with strategic lighting, such as recessed lights or sconces. Finally, display art and photos to personalize the space, ensuring they complement the overall design and draw attention to the fireplace area, creating a warm and inviting atmosphere.
