First, the color of the pattern is uneven, because it is light or heavy when it is put on the pen, or the pigment is too thick. It is recommended that you keep the same strength when you write, and add the appropriate amount of water in the pigment.

Two, when the line is thick and thin, the strength of the line is not well grasped, and the strength should be kept consistent when the line is drawn.

The line is intermittent. The pigment is too dry. Please use proper amount of water and mix it with water.

Three, after painting the dry hands feel hard, first because the pigment is too thick, to add water to reconcile.

The two is to repeat over painting in the same place. Note that when painting the same place, do not exceed three layers.

Four, the lines of the painting patterns leak away, which is the reason why the pigment is too much water, or after the brush is washed, the water is not dried or the clothes are wet.

Five, when painting a wrong line or smear the wrong color, you must not rush to wipe it with water or wash it immediately.

After the pigment is dried, it is first covered with white pigment. After the white pigment is dried, the correct line is added.
