The last time I got really bad service was at the quilt shop I bought my sewing machine from. They didn't fix the problem right away, it took me 5 times of taking it over to them, a 40 mile trip one way, and getting the information off the internet myself telling them what to fix!
I did get 1/2 yard of free fabric for my time! GRRRRRR! I honestly believe we need a review of shops before going to them. A review by other quilters so we know what to expect.
