Explain to me the technique you are using right now:

At the moment the technique I’m using is hatching. Using any type of pencil, you draw thin straight lines from one end of the area you are trying to cover, to the other. The lines you draw go right next to each other to fill the space. There are also techniques like this one, for example, cross-hatching, where you start out using regular hatching to cover an area, then do it again in the same spot, just from another direction.
