The rib structure is often seen in fashion apparel. However, properties of the structure, other than stretchiness, commonly are not considered during the design process. The primary objective of this study was to view the knitwear collection through fundamental knitting factors to explore opacity as a core property of the 1x1 rib knit technique. The experiments were carried out on a Silver Reed knitting machine to define possibilities within layering and opacity ranges, and as a result, the exploration frame was defined. Looking through the textile thinking perspective and consciously using knitting technology knowledge allowed me to use opacity to design layered garments. A collection of five outfits was created where each silhouette’s form and expression was driven by opacity, layering, and knit factors (stitch size, type, and amount of yarn). The project presents the process and outcome of building a knitwear collection through textile thinking.
