This PhD project investigates the relationships between textile patterns, scale and spatial contexts from the perspective of textile design. Against this background, the purpose is to answer the research questions “How can the designer get a better understanding of scale and size in designing textile patterns and what kind of functions and characteristics do different patterns have in spatial contexts?”. It is expected that this practical and methodical approach can offer insights of scale and size issues in designing textile patterns, and may be useful especially for the textile design community.
