Instructions
1. First mix cement, sand, and water completely and set aside.
2. Place the mold in the target position and press it slightly to better fix it to prevent it from moving during operation.
3. Put the concrete in the mold and fill the entire mold.
4. Remove excess concrete from the surface and smooth the surface with tools.
5. Slowly lift the mold up and remove the mold before the concrete is completely dry.
6. Smooth the edges of each part with a wet sponge or another tool.
7. After the concrete is completely dry, use cobblestone and colored grit to fill the gaps. You can also plant grass in the gaps.
