I have a 7700 and love it...I just quilted my King size quilt with ease...I did stitch in the ditch which took me 4 hours which included sewing extra piece of batting, cutting backing and spray basting....I also serged the ends and put in pockets on the corners. In the washer it goes...I will bind during the week. So glad I went forth and quilted it myself instead of paying 200.00 to have it FMQ'd. Yah!!!
