The gouache pen is an important tool for expressing techniques. There are also a variety of options for brushes with adjustable hardness. Pens with different textures can create different effects in the picture.

Shading pen - Shading pen is a sheep's hair pen with a flat tip. The hair of the sheep's hair brush is soft and has a large amount of water absorption. It is suitable for large-scale spreading and dyeing. The contact and transition between brush strokes are relatively natural, and it is used for landscape sketching. The large area of sky, woods and water surface in the medium painting is vivid and vivid with the brush, or used for the background of the still life painting, which looks natural and harmonious.

Oil brushes - brushes made of artificial fibers or pig bristles, with short strokes, firm bristles, and poor water absorption, but the strokes are firm, strong, and elastic. Thick and hard foreground objects, buildings in landscape paintings, fruits and utensils in still life paintings, etc.; it is also suitable for objects with clear outlines and strong reflection, such as wine glasses, knives and forks, metal plates in still life paintings, etc. .
