If you are asking about quilting, the actual joining of top, batting (or wadding), and back by a regular domestic sewing machine, you might check out Leah Day's site. She has TONS of information about how to quilt; from how to arrange your quilt so it's easy to maneuver through the harp of the machine; how to skillfully quilt free-motion designs; all kinds of good stuff.

The short answer to your question is you roll the quilt up tightly to get it under the arm of the machine.
Please forgive me if I misunderstood your question.
