did you talk to her ahead of time and tell her what you wanted? or did you tell her to do what she thought was best? if you chose the second option i don't think you should be (confrontational) she did what you told her to do- if you did talk to her about specifics and she did not do what you requested by all means give her a call- and ask her to re-quilt it.
possibly -- lesson to be learned-- when you take a quilt to the long arm quilter you need to discuss the quilt with the quilter- let them know what you have in mind--even choose designs- if you drop off your quilt and say "do what every you think is best" you will get what the quilter 'thought' was best- it might not be anything close to what you thought would be best.--- long-armer's are quilters--not mind readers--if you don't tell us, we have no way to know
