This study, which was begun in order to create a metal molding by using lines, a basic element of design, examined various characteristics and concept of line and the beauty of lines based on previous research on the subject. The result showed that formative interpretation of lines largely depends on intentional expression by using thickness and rhythm of lines. In order to obtain a metal molding that provides both visual freedom and beauty, rather than the conventional formative expression of lines, I used red copper plate and Phosphor bronze line for creating a pattern based on transformation and repetition of lines and an artwork based on the pattern. The result was not only a creation of a plane but the senses of three-dimension, speed, and unity in the overall shape. Further research will need to be conducted regarding formative interpretation of lines and emotional and intrinsic beauty through expression of lines.
