Why are hatchings used on drawings?
While using hatching or crosshatching in a drawing can create a variety of textures, the technique is mostly used to create a full range of value. The placement of values within the work leads to the illusion of the form of the subject as well as the illusion of a defined light source.
Why is cross hatching important?
The purpose of the cross hatching technique is to create a value range in a drawing. By using this technique, the artist can create the lightest and darkest values, to create a complete drawing. Drawing with this technique is a great way to create the illusion of three-dimensionality on a two dimensional surface.
