You did a marvelous job on every front..I just finished one on my 770, using walking foot and #4 stitch to make the serpentine pattern. Do you happen to remember your length and width settings? I used 2.50 wide and 5.0 long, pieced the lines the width of the left side of the walking foot apart...I love the final product but some of the stitching was a little wonky...would love to know your experience with this.
