This is the first one I cut out--the one where I cut too much from the corners (see previous entry); thus, making it too snug when the darts were sewn in.
I needed a wedge (guess it could qualify as a godet). To make it as simple as possible, I:
--stitched about 1 1/2" of each "dart"; it would be more difficult to turn under the part near the point
--turned under the rest of the sides of the "dart"
--placed the piece which was the original cut-out square and pinned it in place
--topstitched the "dart" sides, catching the wedge piece
Then hemmed it and it's done.
