Since the stitching will be straight lines, you would use your walking foot. I would do a diagonal line across the center one way, then do the other way to form an "X". Then stitch a row on each side of the first line, one going one way and one going the other, then do the same on either side of the second row of stitching. By working from the center and alternating the sitch direction you will minimize distortion. Please let us know if you have more questions!!
