Just curious.
Has anyone used a machine foot like this one to get that 1/4" seam? If you moved the needle over to the 1/4" mark, more of your fabric would be over the feed dogs. I think I will get this foot for some of my other sewing. Often online tutorials (other than for quilts) call for 1/2" seams.

Oops ... When looking at it again, I'm not sure it would work that way for 1/4". Can't quite tell, but the needle opening may not allow you to move the needle that far to the side.
