I wouldn't fret about the mistake. That will make the quilt unique, one of a kind. I myself prefer to make a quilt as individual as I can. I do it because no one else wants something exactly like anyone else has. I would love to see a pic though. I would finish it and give it to a charity. That is my way of throwing it out. Then because your DH suggested it have him go with you to purchase the fabric to replace what you threw out. He will bite his tongue next time. Exspecially when he pays the bill. lol.
