Key purchase considerations for river rocks in the 1-3 inch range include:
- Size and shape variety: A mix of sizes enables both detailed and broad painting, while flat surfaces improve usability for beginners.

- Color variety: A diverse color range broadens design possibilities, especially for mixed-media projects and display pieces.
