I had the Viking MegaQuilter back when I started and it would have come with the Inspira frame but I wanted a wood frame so went to Grace Quilting frames and found the Grace Pro frame. Of course, this was back in 2005 and I have since sold all of it. But I was able back then to find someone that stretched certain machines to 18 inch throat. The Viking, Pfaff, Brother and Babylock machines were a few of them. Also The Juki 98Q and Singer machines. It didn't look pretty but it stitched beautifully. I'm sure the guy that did the stretching is long gone now unless he taught someone to take over for him.
