Yellow Sweater Update

So I finished re-dying my DD's yellow sweater. It was old and kinda dingy. So I freshened it up with Golden Yellow RIT dye and added an applique to the breast. She loves it! But we both though the E could have been positioned better. Also, I'm not sure how or if I should finish the edges of the E. I don't want to take a chance and ruin and otherwise OK project. Hmmm....maybe I could hand stitch something contrasting thread around the edges??
