• Hatching.
It is the creation of lines of different densities and directions that combine to create an image. Hatching can be vertical, horizontal, diagonal, circular, spiral, zigzag, and oblique. It can be even, overlapping, or discontinuous.
• Tonality.
This is the creation of different shades of gray that give the image volume and depth. You can use different hatching techniques, such as cross hatching, dot hatching, or brushstrokes, to tone the drawing.
• Rusty.
This is a technique in which pencil lines and shadows are softened and blended together. It creates a voluminous and soft effect. You can use special tools, such as paper tortillons or cotton swabs, to blend.
• Application of the rubber band.
The eraser is not only a tool for correcting mistakes, but also for creating effects. It can be used to remove individual lines, as well as to form highlights and textures.
