Cultural commodity is a tourism souvenir for tourists with a high added value in terms of economy. When it excellently represents the region and is based upon its tradition, the positive images of the place can be originated. In this way, the formation of benevolent images has economically considerable effects that can promote the competitive power of the area. The purpose of this study is to develop the pattern design of cultural commodity related to Hampyeong Butterfly Festival. The software to be used is Adobe illustrator CS2, which is a Vector Graphic software, and by utilizing the program, the pattern for the cultural goods will be produced. The forms of the pattern are All over Pattern, which is one of the arrangement methods used the most in a necktie field, and Stripe Pattern. After designing with those two patterns, the design is applied on neckties. Like this, by designing through the Vector Graphic software which we can easily get an access to, the concept of design is visualized; therefore, we can prevent the commodity development that can be conducted out of the concept. By making it possible to visualize the examination by various forms or color mixture, the time is shortened, and throughout reproduction of the object, adjustment of the size, colorway, and reusing or remanufacturing the image, we can check the result of design before hand to reduce the time and expenses required.
