I'm so sorry to hear of your LA quilter experience. I am a LQer and always meet with the customer first and discuss the quilt. If I see a problem that may will not quilt out I tell them before I take the quilt so they will know what to expect. What I tell customers regarding warpy or wavy blocks and borders is that when you iron it, if it does not laY FLAT AND SQUARE then it probably won't quilt flat and square. There are thing you can do to resolve those issues, but they don't always work. I would talk with her and see if she can requilt any of those areas.
