I think it depends on your friend. Is she someone who loves what you do no matter what? Then it's fine the way it is, but learn from this for the next one. Is she critical and detail oriented ? Then I might undo the stitching around the edge and add a border and binding. While less time consuming and fabric saving, I'm not a fan of the turn it inside out method of finishing a quilt. Very few of the ones I've seen have a nice straight , clean finish like it sounds like you were looking for. That said, I love the blocks you've designed - there's so much to look at and enjoy along with the clothing parts. Good job!
