What is Crosshatching?
Crosshatching is a technique that utilizes parallel, intersecting lines to shade an illustration. The denser the line spacing, the darker your object will appear. For example, take a look at the French flag below. The left represents dark blue, the middle is white (with some folds), and the right is red. Since the crosshatching density is different, we can tell that the color on the left side of the flag is darker than the color on the right side of the flag.
