Final answer:
To create more volume in art, you should use the higher position on the tool.
Step-by-step explanation:
To create more volume, you should use the higher position on the tool. When using a tool, such as a paintbrush or pencil, the higher position allows you to apply more pressure and create broader and thicker strokes, resulting in increased volume. This can be seen in various art techniques, such as shading or filling in large areas.
