Measure twice....Cut once!
Just be sure that when you mount the backing on the long-arm frame that it is oriented in the right direction or when you get to the end you need to cut 3 inches off one side and add it to the bottom!! NOT FUN!!
Been there, done that!! You're right, it is not fun.
I did not want to remove the quilt from the longarm frame, so sat my SM on it the longarm table and sewed alittle, shifted machine and sewed alittle more. It was a pain.
Another time, I was hand quilting a baby quilt for my boss. When almost done, notice the backing had shifted. Not enough backing left. I had to remove all the stitching and redo. I was thankful it was only a baby quilt, and not larger. Boss was happy, I got paid, but I learned a lesson there too.
