The Pfaff I bought when I was just starting to quilt is called a "Quilt Expression" machine. I can definitely piece a queen or king sized quilt on it but when it came to machine quilting, I had a bear of a time trying to wrestle the quilt through. I did a few large ones in it, but it was just too much of a challenge for me. If you are considering machine quilting look into machines with a large -9" or larger- throat space. I still love my Pfaff for piecing & sewing but I now do all of my machine quilting on my Janome 1600p.
