I am with everyone else on this one, your quilt came from your heart and I can see the love in it even from the photo you posted. Mistakes give it character and its own personality something you will never have with a store bought one. Thats why I love my treadles when it comes to quilting they are a little temperamental at times, but do a lovely job and give it a certain vintage feel to the quilt.
Oh and a little secret I found out is wash the quilt after you finish it up and when you pull it out of the drier all of the wonkiness is not so noticeable and it hides a lot of mistakes!!
