I quilt Kings and Queens all the time on my Janome 6500 or my Singer 201 which I think has as much space. The centre is the hardest part but it definitely is doable. Most of my quilts are scrap quilts that will see a lot of use and many washings. I just can't justify having these long arm quilted. I can do a stitch in the ditch, grid or simple meander and it works for me.
