If you're sending the top to a longarmer, then it depends on the width of her longarm. Mine is 12', but that doesn't mean I can quilt a 12' quilt on it; some space is needed on either side for excess batting and the width of the sewing head. Also you can quilt any width quilt on a domestic sewing machine by quilting in sections. See Marti Michell's book, Machine Quilting in Sections.
