You might want to try this but really enlarge the pattern. I just did it on a long arm, boards 3-5 inches apart, but Leah Day does it on a domestic machine and I used to do all quilting on a domestic machine for over 10 years.

If you spray baste and pin the edges every 4 inches you'll be fine running your machine from one end to the other. If you decide to do only stripes and use a walking foot be sure to set the stitch length to about 3 on your dial.
