I love it - and I know your mom will, too. I'd do SID to define each area and then change the type of quilting. I like the echo quilting idea around the vase and flowers, and the grid for the blue area (blue painters tape, the wide one, is a good way to keep your lines straight and you can re-use it). I wouldn't quilt really densely, but a more open, loopy version. Google for some examples and practice a bit first. I can't tell what size your quilt is. Be sure to do a label for the back, and maybe include a picture of the two of you printed on fabric, attached to the label? That would be a really nice touch, coming from a mom who is probably fairly near to your mothers age....I know I'd love it!
