I am so sorry you are having this experience; it takes a lot of work and time to make a quilt and if she agreed to a price beforehand then she should stick to that. I beleive the $126 is more than reasonable and she should actually be offering you more, I agree that if she is not willing to pay then just keep it or put it up for sale or what you feel you would like to do with it. Very detailed and lots of time spent with materials plus your design, you did a wonderful job!
