Buying Guide
What size should you choose? For tiny detailed designs, pick 0.5-1.0 inch stones. For mid-sized scenes, 1.5-2.5 inches are ideal. For bold statements or large murals, opt for 2-3 inch stones.
Which surface is best for painting? Flat, smooth surfaces show paint evenly and reduce streaking. Look for stones described as flat and smooth with minimal pits.
What should I know about natural variations? Natural rocks vary in color and texture. Some kits note texture or color differences; this adds character but may affect uniformity in multi-stone designs.
Are these stones safe for kids? Most sets are suitable for adults and children with supervision. Avoid tiny stones for very young children to reduce choking risk.
Which sizes mix well? Multi-size kits provide the most flexibility, letting you combine small details with larger fields of color in the same project.
