When I enter into a long term relationship with any business or vendor, I always try to remember to tell them this:
I can deal with just about any issue that comes up, provided you tell me what is going on. If you make a mistake, miss a deadline, whatever, TELL ME. Otherwise, I will feel like you are hiding something from me or ignoring me, both of which are worse than me knowing about the problem.
I hope your quilt comes back to you safe and sound.
