So I did not try to finish the quilt late at night. And it is looking great! Or great to me, anyway. I'm excited. I pinned the batting to the back panel, sewed it down 1/2" in from the edge, trimmed the batting (so it was not sewn into the next seam, making it bulky), pinned the top to the back and batting, sewed the edges, turned it right side out, pinned top to batting and back, then ironed and sewed along the edge again to keep it from shifting. Is this a standard way of putting a quilt together? I imagine it doesn't work as well with larger quilts. Now I have to tuft it, and it's done!
