Design and Development of Bag Patterns Inspired by Local Flora Using the Silk-Screen Printing Technique: A case study of Dok Khii Kak

Abstract

This research consists purposes were 1.  to analyze the visual and aesthetic characteristics as well as the cultural identity of the local plant known as “Dok Khii Kak”, focusing on form, color, and structural composition, in order to establish conceptual guidelines for the creation of bag pattern designs 2. to design and develop bag patterns inspired by Dok Khii Kak through the application of silk screen printing techniques that are aesthetically appropriate and compatible with the materials, functional requirements and contextual use of the product and 3. to evaluate the design quality of the developed patterns and bag products in terms of aesthetic value, coherence with local identity, appropriateness of production techniques, functional usability and potential for commercial application and value creation. This study employed a mixed-methods research approach integrating both qualitative and quantitative methods. The research instruments included interview guides, questionnaires for preliminary data analysis and concept synthesis, questionnaires for evaluating sketch designs and bag product prototypes, and questionnaires for assessing the developed patterns and final bag products. The sample group consisted of 50 participants selected based on predefined criteria, while the target group comprised 3 key informants selected through purposive sampling. Quantitative data obtained from the evaluation questionnaires were analyzed using descriptive statistics, including percentage, mean, and standard deviation. Qualitative data collected from documents and in-depth interviews were analyzed using content analysis. The research findings show that 1) Dok Khii Kak is a local plant characterized by distinctive floral forms, inflorescence structures, and natural color tones that reflect simplicity and harmony with nature. These characteristics can be synthesized into key visual art elements, including line, form, rhythm, and tonal value. Moreover, Dok Khii Kak has not been widely utilized as a source of inspiration in product design, indicating its strong potential for creating a new product identity, enhancing the distinctiveness of community-based products, and promoting a renewed perception of local natural resources 2) The developed patterns can be categorized into primary and secondary motifs to ensure appropriate placement and flexibility across different areas of the bag surface. The design process emphasized a balance between aesthetic value, local identity, and practical usability. Natural color palettes consistent with everyday usage contexts were carefully selected, resulting in patterns that harmonize with the bag’s form without interfering with functional use and 3) The overall mean evaluation score was at the highest level of appropriateness (x̄ = 4.60, S.D. = 0.31), indicating that the developed patterns and bag products demonstrated high quality in terms of design, identity representation, and potential for commercial development. Additionally, the evaluation by general users showed an overall mean score at a high level (x̄ = 4.36, S.D. = 0.56), reflecting that the developed bag products effectively met user expectations regarding aesthetics, functionality, and market appeal.
