Oh I just can not imagine quilting a King on a domestic machine. I have heard it can be done... but I am of the opinion that having my quilt done by a pro is the best gift I can give myself. I just dread quilting a large quilt on my domestic machine.
Just a note I have mailed quilts out alot .. and I did have some apprehension at first ... but now .. I have no concerns.. just get the tracking . But I am sure your local shop can refer you to some longarmers... but there are some very talented members on this board.
