Another idea is to quilt on your home machine in thirds.
Layer your top, batting and backing. Pin or spray the center section. Gently fold back the top third and cut out that piece of batting only. Do the same for both ends. Quilt the center 1/3. Add the batting back to one end and quilt and then the other end and then quilt
You will only be quilting about 40 inches at a time, so much easier to handle on a home machine. I use a little basting spray on the edges when I'm putting the batting back in the sandwich. Don't overlap but butt to the edges.
Works very well.
