Here is a video of a Davis NVF machine (one like mine) in action.

Notice that the machine doesn't have feed dogs and that the foot moves the fabric.
These machines are awesome to quilt with and attach bindings. And the machine handles quilting flannel without any problems.

I own two of these machines. The difference in the two machines is the tension area. They take standard needles.
