Choose miniature plants, such as succulents or moss, to represent the causal sets, arranging them in a visually appealing pattern. Add tiny decorative elements like small stones or figurines to enhance the display. Water sparingly and place the box in a shaded area to maintain its beauty. This simple DIY project transforms any outdoor space into a charming, small-scale garden masterpiece.
