Congrats on your Avante'. Lets see what we can try to get you going. Once your bobbin is set, creeping down like a spider, you should only have to adjust your top tension. Try loosening your quilt top a little. Having it to tight can break the thread. If your stitches are consistently skipping you can tweek your needle a tad to the 7:00 position. If your thread is still breaking you may have to loosen your bobbin and top tension both. Try one thing at a time. Good luck, any problems, you can PM me.
