first, you need to look at your batting packaging. It will tell you how far apart the maximum is that you can quilt. You don't want this cute quilt to get all bunched up in the first wash. Hopefully, you haven't chosen something that needs to be quilted 3" apart. I would outline the girls and their dresses, adding a few lines of quilting in the dresses as needed to meet the batting requirements, then stipple everything else all the way to the edge.
