If it works for you, do it! Having quilted a large queen size on my trusty, old Bernina I really appreciate anything that makes it easier. I have found though that using bicycle clips does not work if they are the type covered in rubber. The rubber sticks to the bed of your machine and table top, making a difficult job even harder.
Another tip, instead of crumpling your quilt up to fit in the throat of your machine, roll it up. It makes it more compact and easier to go through the limited space.
