The basic line drawing methods of sketch are as follows:

1, pay attention to the connection between lines, with heavy force in the middle and light writing and handwriting. When arranging the cable, the short wrist exerts force, the shaft is on the wrist, the long arm exerts force, and the shaft is near the shoulder. The lines made by the arms should be straight and the strength should be the same, so that they don't look like long hair.

2. When laying cables, you can lay more layers in dark colors, and the lines in bright colors can be sparse. When drawing an object, we don't just draw a stroke at a glance. An object is just a type and a model. It is necessary to find out the dividing line between light and shade and highlight it, and make full use of the five tones of understanding light and shade. First, make sure that a picture has been formed in your mind, and then express it slowly.

3. Then there is the question of gray. Generally, the painting is very gray at first, and the solution is to open the black and white gray. It was more difficult at first. If you draw more, the things you draw will be three-dimensional, and the black, white and gray will be clearer. Of course, when sketching or copying, beginners should first find the brightest part and the darkest part in the middle of the painting, and then draw the darkest part of the painting with 6b.

4. After painting, squint and compare the still life with your own painting again. In the final modification stage, the bright part is brighter and the dark part is darker. The dividing line between light and shade will be slightly stuck, and you should also use a line card, not a single line and not a border.

Benefits of learning sketch:

1, through the observation and painting of geometry, let children understand perspective and cultivate their three-dimensional sense and spatial imagination. Complement the study of other subjects. For example, if you don't draw figures, you already have three-dimensional figures in your mind.

2. Draw a good sketch and pay attention to observation methods and comparison. As a result, children's eyesight and comparative ability have been exercised.

3. Cultivate children's carefulness and patience.
