Why Soil of the Garden is not Suitable to Make Models?

Soil in a garden may not be suitable for making models because it tends to be too soft and inconsistent in texture. It may not hold its shape well, making it difficult to create durable, fine details. Models often require more stable materials like clay, plaster, or other sculpting mediums that can be shaped, hardened, and maintained. Soil can also be prone to cracking or crumbling as it dries, limiting its effectiveness for detailed model-making.
