Lady layers plastic bottle bottoms with glue. This DIY keeps popping up everywhere

To add more dimension to your accent wall, consider using bottles of different sizes and shapes. You can also experiment with various painting techniques, like ombre effects or stenciled patterns, to create different visual textures. For a more natural look, leave some bottle bottoms unpainted or use translucent paints that allow light to pass through, creating an interesting play of shadows. Additionally, you could integrate LED lights behind some bottle bottoms to create a glowing effect, adding another layer of depth and interest to your accent wall.
