Line design refers to the arrangement and organization of lines in a visual composition. It plays a crucial role in various fields, including graphic design, architecture, and art. Lines can guide the viewer's eye, create movement, and establish a sense of structure within a design. In line design, different types of lines—such as straight, curved, thick, or thin—can convey different emotions and messages. For example, curved lines often suggest softness and fluidity, while straight lines can imply stability and order. Understanding how to effectively use lines can enhance the overall impact of a design.
