Pens that can be used for line drawing include pencils, charcoal pens, charcoal sticks, pens, nylon fountain pens, signature pens, marker pens, etc. Line drawing is a kind of sketch, also known as line drawing. The feature of line drawing is to draw with lines, and to create different picture textures according to different lines, such as straight lines, curves, broken lines, parallel lines and intersecting lines. And according to the density of lines, it shows different light and shadow changes.

Line drawing can be divided into single hook and double hook. The single hook is painted with the same color brush, and the double hook is painted with different color brushes many times. Although there are only simple lines in line drawing, the different textures and depths of the lines make the objects full of charm and lifelike. Pay attention to the smooth and natural tick marks, and the drawn works are concise and clear.

Because the single hook uses a brush of one color, the depth of the color is very important, and the painting drawn with this line is accurate, vivid, coherent and smooth. The tool for drawing lines is not only a brush, but also a flexible choice according to your own needs. Line drawing is also the basis of painting, and it is also the entry choice for children to practice painting. If you want to draw a good line drawing, you should not only practice more, but also learn to observe. Only by observing and determining the structure, outline and characteristics of the painting object can we show our charm through painting.
