First of all, practice using the center and avoid the winger. The center pen is full and elastic, with rounded lines and strong feeling; The petals and leaves in the flower are thin sheets, which should be outlined by the center. The side front is only used when rubbing trees and stones. When you start to practice hook line, it's easy to hit the side, especially at the corner of the line. Because the brush is conical, it is necessary to lift the pen when rotating, and gently rotate the torsion direction of the pen tube so that the pen tip rotates parallel to the circle, so as to keep the center. The key to the strength of lines lies in the friction between the pen tip and the paper. Some people don't dare to hook the line hard for the sake of thinness, and the hooked line slips on the paper and doesn't meet the requirements. When hooking the line, you should press the pen downwards, so that the pen tip has pressure on the paper surface. At the same time, you should hold the writing brush, which has an upward lift and two forces are balanced, and then use a drag force to write. If you don't mention it, you will be prone to one-sided; Just lifting without pressing is floating, and the line is weak. Don't tease, pick or slide the lines. So each line should have three actions: start, write and receive.
(1) Start writing hidden front: If you want to write to the right, write hidden front to the left first, and then write to the right. This is called first left and then right, and vice versa. The same is true of the last pen. You want to go down first, and you want to go up first, so there is friction between the pen and the paper.
(2) Line pen: The line pen should be steady and slow, and the pressure on the paper should be even. There are various changes in paddling, such as stopping for a while, turning back when encountering setbacks, adjusting paddling direction when encountering setbacks, and not paddling sideways. When the middle ring is turned with a pen, the flank becomes wrinkled.
(3) Put the pen back in front: every time you collect the pen, you should take it back in the same direction. The so-called days are gone forever, not drooping or shrinking, which makes the end of the line subtle and powerful.
We should also pay attention to all kinds of pen and ink changes in the practice line, such as center and flank, forward and backward, and pen changes such as setback, turning, thickness, breaking, Fiona Fang, sudden illness, darkness, and virtual reality. , plus shades, dry and wet ink color changes, to meet the requirements of formal beauty in line drawing.
