What is the main purpose of both hatching and cross hatching?

Correct answer: Creating value and shadow with lines

Answer: D, creating value and shadow with lines. Hatching is shading made from a series of mostly parallel lines. Cross hatching adds another set of lines crossing the first set. By changing line spacing, direction, length, and sometimes pressure, the artist can suggest lighter and darker areas. Closely placed or layered lines usually make an area appear darker, while widely spaced lines leave more paper visible and appear lighter. These changes help describe volume, light, and shadow. D is correct because both techniques use line marks to build value. A is incorrect because hatching does not directly change the hue or colour family, although coloured lines can be used in some artwork. B is incorrect because the paper remains a support and is not folded by the technique. C is incorrect because making a frame is not the purpose of repeated shading lines. Memory cue: hatching shades in one direction; cross hatching shades by crossing directions.
