It depends on how large of a throat space you have but a lot of quilters still are able to quilt queen size quilts on their domestic machines. You just stuff the quilt through the throat. Also quilt only about 1/4 of the quilt at a time. So you start out in the middle and work one quadrant at a time, for example the lower right corner. Then you might do the lower or upper right quadrant and so on until you're finished. So you're really never stuffing the whole width or length through the throat at one time.
Good luck and show us pictures.
