Create a logo concept for sewing, influenced by the flat and abstract design trends of the 1980s, while still embodying Swiss-style simplicity. As a traditional Swiss manufacturer of sewing machines, the logo should convey a sense of modernity and innovation within a minimalist framework. Experiment with geometric shapes and bold, clean lines to create a visually striking composition. Emphasize simplicity and abstraction, using subtle references to sewing or craftsmanship to maintain a connection to Bernina's heritage. Ensure the logo communicates the brand's values of quality, precision, and family tradition, while capturing the essence of 1980s design.
