So sorry you had a bad experience like this. Since size can be a subjective thing ("Large", "Medium", "Small" ), I have a pic of meandering examples that I show customers with a ruler laid across it for scale so they can see what my interpretation of those sizes means. I think and hope it helps to avoid miscommunication. If I were you, though, I would definitely tell her about the fold since it indicates a lack of attention to the tautness of the backing and/or batting.
