Working with tricot, ribbon or lots of layers? The innovative BERNINA Dual Feed is built-in to the 830 to give you the most control when your fabrics are hard to manage. For even more control, the BERNINA Dual Feed can be fine-tuned to your specific fabric----great for velvet. This innovative feed system offers the ultimate in visibility and maneuverability, too. Then, when you choose, it flips up and tucks away. The optional walking foot is another fine choice, especially for outline, channel or grid quilt
