I'm doing a wall hanging that's 21 inches wide by 29 inches long. The batting says to quilt 1-4 inches apart. Do I need to follow this for something this small? My background fabric is the ocean with waves and I don't really want to clutter it with a lot of quilting. One area unquilted is the length of the wallhanging by 6 inches wide. This has a nautical theme and I really don't know how I would quilt it if I had to.
