From another handquilter: As I see your quilt of 6 inch squares, if it were my quilt, I would quilt a small design in the lighter colored squares and also stitch in the ditch around these squares . I would crosshatch the rest of the top in the diagonal, maybe 1 in apart. My reasons for doing this: Pretty designs show up best on light colors, and, for me, diagonal quilting is quickest and easiest stitching. Just my ideas, lots of good ones here for you to chose from. Happy quilting!
