@Seifer: I know how to do a line and satin stitch, but other than that, I'm completely lost. Line stitch makes me think of hand sewing just looks fancier and bigger since it's with embroidery floss.
Thank you for the link! And for the suggestion, I'll do a test of this on scrap fabric before I do it on the cape fabric. I have had bad tendencies to horribly screw up things - it's why I always buy more fabric than I need.
