The basic tools for sketching are: pencil, charcoal pen, pen, paper, drawing board, eraser, pencil sharpener, thumbtack, wiping cloth, etc.
1. both 4K and 8K sketch papers are acceptable, but 4K is more suitable for modeling. the choice of 4K or 8K depends on the size of the painting you want to draw.
2. A flat and soft square rubber is better. And plasticine, plasticine is easy to change shape, so it is suitable for various wiping, but its cleaning and modification ability is average.
3. At the same time, there are many kinds of pencils, such as hard ones, soft ones, deep ones and shallow ones, which are relatively complete, and can draw more tones. The color of pencils is also convenient to show many silver-gray levels in the tones, which is effective for basic training operations such as gypsum and easy for beginners to grasp. Therefore, it is more suitable for application at the beginning of basic training. ?

Types of basic sketch techniques
(1) Line and line techniques
The element of sketch is line, but it does not exist in essence. It only represents the boundaries of objects, colors and planes, and is used as an illusion of objects. It was not until modern times that lines were considered as spontaneous elements of form and independent of the depicted objects.
(2) Form the image of an object with lines
Sketch is to form the image of an object with lines and draw it on a plane, that is, the line form causes the viewer's association. For example, the angle formed by the intersection of two lines can be considered as the boundary of a plane; In addition, adding a third line can create a three-dimensional effect on the picture.
Arc-shaped lines can symbolize the vault, and intersecting lines can express the depth. People can get comprehensible images from the changes of lines. Therefore, through the means of lines, simple outline can be developed into exquisite sketches.
(3) Use lines to distinguish between solid and plane
In sketch, lines can be used to distinguish between solid and plane. As for color shading, it is to strengthen and distinguish the relationship between the whole and the parts. We can use the beginning, disappearance and interruption of lines to draw boundaries and form a plane, or we can make colors go up to the boundaries. The thickness of lines can show the changes of objects, and even light and shadow can be shown by the changes of strokes of lines.
(4) the assistance of plane technique
The line technique of sketch also needs the assistance of plane technique. When using charcoal chalk in plane technique, the brush-wiping method can be used in contrast between light and shade.
(5) Use of brush painting
It is more important to use brush painting, because brush painting can give full play to the width of strokes and the intensity of strokes, and increase the sense of space and three-dimensionality.
(6) Enhancement of artistry
Multicolor brushes can also be used as basic materials for sketch to enhance the sketch effect and artistry.
