I'm with Pam.
At first I didn't use my walking foot, thinking it was a very strange object. A sewing teacher told me to give it a try. I finally did, and now I rarely take it off. I take it off for stitch in the ditch, and when I use my BSR. And then of course, if I have to use a specialty foot. But my sewing improved a whole lot when I started using my walking foot.
