1, dip a small amount of water with a clean brush to make the pen wet.
2. After the brush is dipped in water, lightly brush the surface of the pigment to make it fully dissolved by the water on the brush.
3. After dipping the paint, rotate the brush back and forth in the palette to let the brush fully absorb the paint. Observe the ratio of water to pigment. The amount of water determines the depth of color.
4. When there is too much water in the pen tip, you can suck a little water with a paper towel.
5. Gently draw excellent blocks on the drawing paper with a brush.
