Although the lines seem simple, they are difficult to draw well
The way the line can be expressed is flexible and diverse
It can be long or short, ancestral or thin, curved or straight
A lot of drawings are just getting by when they draw new drafts
As soon as I got to the line drawing stage, I felt that I couldn't hold it
Today we will show some brushstrokes and rubbing techniques for line expression
The following points are summarized in a nutshell:
▼
1. Elongate the line
The tip of the pen is slightly sideways or directly lying flat on the paper,
The pen is light, the middle pen is fast,
Collect the pen and return the same trajectory movement,
Pay attention to the movement of the arm and wrist in a unified direction.

This line is often used as a summary of the shape at the beginning of the draft
and auxiliary grasping, centering axis, etc.,
It is necessary to practice pulling the line in different directions.

2. Wire arrangement
There are many types of lines
Use different lines depending on the situation
Here are the types of lines
straight line
The most basic of straight lines are vertical and horizontal. When you practice drawing straight lines for the first time, you should control the smoothness of your wrists. Using the side, flat or center of the pen, you can draw evenly equidistant straight lines, oblique lines, horizontal lines, long lines, short lines, thick lines, thin lines, straight lines with light tops and heavy bottoms, and straight lines with heavy tops and light bottoms.
Arrangement of straight lines
There are many different directions and methods of arranging the lines, such as arranging from the top right to the bottom left, from the top to the bottom, and from the left to the right. The tone in the sketch is expressed with the help of lines. Using different tools and mastering different wire forms and methods, you can express rich tones and textures of objects.
Straight line arrangement at different pressures
By changing the strokes of the pen and appropriately changing the pressure of the nib, it is possible to draw lines of different shades. In sketching, the sense of space and volume of objects is often reflected through the virtual and real lines.
When arranging the wire, it is required to use even force. Lines should be avoided as deep at both ends and shallow in the middle. Lines should be staggered with each other and should not be perpendicular to each other.
Straight lines that intersect each other
Shhhh
curve
The curves have a sense of rhythm and flow, which can emphasize the sense of volume of round objects; The smallest unit of a curve is an arc, and the combination of arcs can form an S-shaped line or an X-shaped line. Curves can represent objects with arcs, spherical objects, or textured objects, etc.
Arrangement of curves
When arranging curves, you can accurately depict the texture of the object by adjusting the density, thickness, depth, curvature and other elements of the curve combination.
Curves that intersect each other
Zigzag lines
Zigzag lines are lines that are in the shape of a "Z", which are mostly used for flat painting, and the strokes of the lines are not very obvious, which is suitable for expressing soft and smooth objects. When drawing this kind of line, it is more likely to be drawn with the pen lying down.
Zigzag lines that cross each other
Short
The short line is actually to draw different permutations and combinations of lines with shorter strokes, and you can speed up the speed of using the pen when practicing the drawing of short lines, and there is a certain rule when arranging, which can be used to draw texture or hair.

3. Lines are combined to form surfaces
H. The effect of mesh combination is more commonly used
Pay attention to the layers of line superposition should not be too much,
so as not to make the picture airtight.

I. Use the pen to move the pen sideways, and the pen movement is uneven
Surfaces with light and dark changes can be directly displayed.

4. Rubbing technique
Maybe you often see teachers demonstrating
Rub your finger on a certain part of the picture and it will feel dirty
In fact, this is one of the most commonly used techniques in painting
"Wipe" (or "wipe")
The pen and paper belt rotate unevenly with the pen strength,
It is usually used to rub out the gray surface.
Combine the lines into a surface and then wipe it flat with a pen and paper,
It is usually used for uniform color block processing.
Wipe with a folded paper towel vertically,
It can make the tone appear richer and more varied;
If you rub it with a paper towel, you can also let the paper "eat" the charcoal;
Rub with a paper towel in the same direction as the line,
It is easy to show a loose light and dark effect.
Re-rub with your hand in the direction of the line,
It is convenient to depict subtle changes in tone in shiny areas.
