The BERNINA Cordonnet Foot #11 is the perfect choice for topstitching and decorative work with cordonnet thread or other thicker topstitching threads. Its sole features a 2-mm-deep groove that allows for smooth gliding over thicker threads while ensuring consistent fabric feed. This versatile foot also facilitates precise sewing of sashiko patterns and other decorative designs. A helpful tip when using Cordonnet Foot #11 is to pair it with a needle that has a sufficiently large eye, along with normal bobbin thread, and make tension adjustments as needed for optimal results. Furthermore, this foot is compatible with a wide range of BERNINA sewing machines, spanning from entry-level models to the high-performance BERNINA 8 Series.
