Optional: Apply a coat of acrylic varnish spray for a glossy finish and added protection.
Fill terracotta pots or shallow decorative bowls with sand or small pebbles.
Arrange the painted stones in the pots or bowls to create the look of a cactus garden.
For variations, try using different shades of green to create a diverse cactus garden. You can also experiment with different patterns and textures, such as stripes or zigzags, to add interest. Consider adding small painted flowers in bright colors to some of the stones for a whimsical touch. If you prefer a more natural look, use muted pastel colors for a subtle effect. Adjust the arrangement in larger planters to create a statement centerpiece.
