Line design refers to the arrangement and organization of lines in a visual composition. It plays a crucial role in guiding the viewer's eye, creating movement, and establishing a sense of structure. Lines can vary in thickness, length, and style, influencing the overall mood and message of the design. In various fields such as graphic design, architecture, and fashion design, line design is essential for creating balance and harmony. Different types of lines, such as straight, curved, or diagonal, can evoke different emotions and reactions, making line design a fundamental element in visual communication.
