Sorry about sounding like a party poop - but - unappealing as unsewing it and redoing it is - will you be happy with the way it is?
It's your quilt - and you are free to do - or not do - what works for you.
For ME, having a mistake (or as some would say - a "new design element") I know about and can correct - and not doing so -
It would be the same as wearing dirty underwear inside out and backwards. It would bother me.
