The BERNINA Cordonnet Foot #11 is expertly designed for topstitching and decorative sewing using cordonnet thread or other thicker topstitching threads. With a 2-mm-deep groove beneath its sole, this foot glides effortlessly over thicker threads while ensuring consistent fabric feed, making it ideal for smooth and precise sewing of sashiko patterns and various decorative designs. For optimal results, it’s recommended to use a needle with a sufficiently large eye and normal bobbin thread, adjusting the thread tension as necessary. Cordonnet Foot #11 is compatible with a wide range of BERNINA sewing machines, from entry-level models to the advanced BERNINA 8 Series, enhancing its versatility for all sewing enthusiasts.
