I think communication is number one and understanding. I have lots of quilts done and I am now searching for a regular LA'er, since mine is not doing it anymore. There was only one quilt that I ever had done that I was not happy with, and it was just that the quilting design had too big of space between the repeats, that disappointed me. But I still put alot of trust in the LA'er, you have too.
They have a talent that is all their own and I appreciate their work.
