I was reading a quilt book that I got for my birthday "Mastering Precsion Piecing" by Sally Collins. One thing that I found very interesting is that she says if we have a machine on which you can move the needle over, we really should be using a wider presser foot and moving our needle over until we have a 1/4" or scant 1/4" (whichever you prefer) at the edge of that foot. For most of us - I have a Bernina when we have our needle in the center position and use a 1/4" foot we are not using the feed dogs on the right hand side which gives us better fabric control. I haven't tried this yet but will on my next project. It is one of those aha moments and makes sense after someone tells me that.
