First, collect some information, pictures and words about the spring outing of primary school students. Then use a watercolor pen to draw, the header can be designed with pictures, and the middle illustration should be set with words floating on the pictures. The middle text can be colored and the background can also be colored. But pay attention to the readers. Because it is a pictorial for primary school students, we should use bright colors in color matching. Children are more interested in pictures by using illustrations.
