How can you achieve a sense of form with contour drawing?

To achieve a sense of form in contour drawing, focus on capturing the outlines and edges of the subject while maintaining an awareness of its three-dimensionality. Use varying line thickness and pressure to suggest depth and volume, emphasizing areas that recede or project. Incorporating subtle variations in line quality can also help convey texture and light. Practicing continuous line drawing without lifting your pencil can enhance fluidity and reinforce the sense of form.
