I quilt on a longarm, but the theory is the same. Start with your bobbin thread up on top of your quilt top and when you end, pull up your bobbin thread. I tie them just like I would if I were hand quilting and bury them in my batting. Going forward and backwards to secure the ends is also something you can do, but I just don't like the way it looks, so I don't do it. Post pictures when you are finished with the quilting!! Also, if you can sneak and stitch in the ditch a bit or plan your path well, you can do different kinds of custom quilting without stopping.
