Pfaff Quilt Ambition 620 Sewing Machine

8.5 Overall Score
> > > > >

The Pfaff Quilt Ambition 620 is a popular quilting machine. It also works well on knit fabrics because of the Pfaff IDT™ system, which feeds fabric layers evenly without the need for a walking foot. Even with that feature, it doesn’t perform as well overall as the other higher-priced machines in this article—especially on heavy fabrics.

If you’re a serious quilter, this could be the machine for you. If not, buy a Juki. Honestly, even if you are a serious quilter, you should probably just buy a Juki (I promise I’m not sponsored!).
