This sounds like a great idea to use up left over charm squares. Do you think using a 5" square would be too small?
Why couldn't you sew all around the pentagon and then put a small slit in the inner pentagon to turn the piece. I would place the slit somewhere near the "fold" line so it would be covered up by the triangle fold.
