I am so sorry you are unhappy with your quilt. I hope you can get it fixed to your satisfaction. I would expect any LA'er to give a written estimate up front, and that the estimate would have all the notes as to what would be done for that price. However, since they didn't, and you didn't ask for one, that muddies the water considerably. From what you describe, it doesn't sound like it should have cost that much, but I don't know what the going rate is in your area. It may be that they charge so much per inch for custom quilting, and don't factor in how much actual quilting was done. It does seem like a huge jump from $210 for a queen to $350 for a king - that's a 66% jump, and a king isn't 66% larger than a queen. It will be interesting to see what they tell you when you go in to talk about it. Perhaps they just made a mistake in the pricing? Hopefully it wil all be resolved to your satisfaction, so go in with the attitude that it all can be worked out.
