You did a beautiful job on the piecing, now hand quilt it like it deserves. As a hand quilter I would echo the pieced seams by 1/4 inch on either side and outline the appliques. If there is room in the borders use a simple curved chain or pattern that gives it a little rounded touch. I know that most on this board seem to be machine quilters but hand quilting lets you stay in touch with your work and for goes all that rolling and wrestling to get a bed size quilt under your machines needle. A quilt that lovely deserves to be handled with loving care.
