Sketch usually uses methods that can leave traces on the plane: such as charcoal pen, pen, brush, ink, paper and so on. Outlines and lines are general terms for sketches. Sketch has a feeling of natural law. Different strokes create different lines, intersecting relationships and rhythms, active and passive surroundings, planes, volumes, tones and textures.
Sketch is a formal artistic creation, which uses monochrome lines to express things in the intuitive world, as well as ideas, concepts, attitudes, feelings, fantasies, symbols and even abstract forms. It does not pay attention to the whole and color like color painting, but to the structure and form.
There are many tools to expand data sketch, such as stone pen, charcoal pen, iron pen, chalk, writing brush, pencil and pen. There are also paintings of diamonds and diamonds. Different tools are related to the nature and composition of sketch, and tools will also affect the painter's mood and skills. The choice of tools depends on the artistic effect that the painter wants to achieve.
Generally speaking, dry pen is suitable for making clear lines, and ink pen is suitable for expressing planes; Exquisite strokes can be brushed with a brush, and vast fields can be outlined with a pencil or chalk. Charcoal pen can be used for both. From the size of the work, large-scale sketch works are suitable for drawing with charcoal pen, and the outline and carefulness can be carefully studied and analyzed for a long time.
As for pencils, they are suitable for smaller sizes. There are few large pencils, while pen-and-ink drawings are even smaller, and they are often used for illustrations. The monochrome performance of sketch makes the tool very random, and it can often be used comprehensively to create a variety of picture effects, so it is a very broad world.
