Hatching and Cross Hatching

We learned about these techniques last year, so I thought I would go more in depth and explain it more, maybe learn some more about it and try out what I learn and post pictures. But for now I found some examples online.

 These are the types of Hatching and Cross Hatching.
Linear hatching

Hatching in parallel lines. Normally the lines follow the direction of the described plane.^[

Crosshatching

Layers of hatching applied at different angles to create different textures and darker tones. At its simplest, a layer of linear hatching is laid over another layer at a 90° angle, to which further diagonal layers may be added. Other methods include layering arbitrary intersecting patches. Crosshatching in which layers intersect at slight angles can create a rippled moiré effect.

Contoured hatching

Hatching using curved lines to describe light and form of contours

Hatching and Cross Hatching are shading techniques. They represent ripples in clothing, and different layers, further away or closer, and they also represent shadows and other important details to add into drawings.
