Yep, I also move my needle over a couple of notches to the right on my machine so that the fabric is covering all the feed dog. If I don't, the fabric gets pulled through unevenly. I use that ruler that Bonnie Hunter recommends to find your "perfect" scant 1/4" seam. However, I think someone gave me a reason once not to do that but I don't remember what that was. So, I continue to move the needle over the same amount every time I sew a 1/4" seam.
