Hi Koriana,
I had a similar experience as your son. When I was in my teens I made a log cabin quilt that did not square up. So frustrated, I put it away and it never saw the light of day from me. Many years later my mom secretly had it finished for me - squared and reassembled. This meant so much to me. I know I would not have liked it to be finished as it was originally (sounds like your son). I am now going to give it to my grandson. I hope this helps in your decision.
