I measure in the middle and then quarter my quilt and mark with pins on the quilt and border, and then ease to fit. I was showing someone how to do this, and she was questioning my method. We measured the border, if she did the sew and cut method, and there would have been two extra inches in the border. That was on a baby quilt, so it does make a difference. I have friend who does long arm quilting as a business, and she is so frustrated with the sew and cut method quilts, as it is really hard not to have puckers when quilting.
