When drawing with marker, if you use square tail, you will also encounter the situation that the details are not expressed in place. Because of the special shape of the square head, it is not very convenient to control, and many painting details are difficult to accurately show. At this time we can use the thin round end of the marker. When painting at one end of the round head, you should also pay attention to the speed of painting to avoid leaving dark traces of overlapping strokes at low speed. Attention should also be paid to drawing details with thin round heads. If the intensity is slightly greater, the lines will be thicker, lighter and more delicate.

The nib of marker pen is tough, easy to control coloring, thick in color, high in saturation and bright in color. Therefore, architectural design renderings, landscape renderings, interior design renderings, clothing design renderings, jewelry design renderings, industrial design renderings, landscape figure sketches, cartoon figures, plane posters and many other painting themes can be represented by marker pen, and the application of marker pen is increasingly extensive.
