Okay - I've got a dumb question here. I used the graph idea and found that the 1/4 inch on both of my sewing machines (good and cheaper) both miss covering the "right" feed dogs. So, Ideally I should adjust the needle so that the 1/4 inch includes that right set of feed dogs (for an even feed?) or don't worry about it feeding over the right feed dogs? (Told ya it was dumb) but I am a new quilter. Thanks.
