What does cross-hatch mean?

Cross-hatch refers to a drawing technique where intersecting parallel lines are used to create shading, texture, or depth in an image. By varying the density and orientation of the lines, artists can achieve different tonal effects. This method is commonly used in pen and ink illustrations, as well as in various forms of graphic art. Cross-hatching can also refer to the overlapping of lines in other contexts, such as design or drafting.
