IF the seam allowance switches (that happens to me a lot), starting a few stitches BEFORE the switch (and still tugging the seam a bit) maneuver the line so the needle slowly moves over to the other low seam and continue sewing until the seam allowance switches again. When the quilt is washed, all will be well. Don't give up.
This is what I do. I love my SID foot; it allows me to secure much or all of the quilt so that I can remove most of the safety pins used for basting before I do any other quilting.
