Quilting with the Bernina 820

Some additional information regarding twin needle stitching on the 820. I have discovered that it is essential to set the twin needle security before threading the machine for the this work. The security function ensures that the swing of the needles will not be wide enough to break them, and apparently influences the threading as well. I have not tried this yet, but was interested to learn this fact. As soon as I finish my entry for the Tasmanian Quilt show I will try this technique again.
