I only long arm for myself, but yes, I check the back as I go. Each time I roll, I look at the part that I just quilted. I float my batting and my top, so before I start the next stitching, I check the back part coming up. I should add that my older long arm machine can throw it's own little fit every once in a while, and I have had to rip out the last row of panto stitching more than once, therefore, I am extra diligent. I can reload, but I don't like too.
Edited to add: It sounds like she didn't clamp the sides to stabilize them. If she has a 30" Longarm, that would be one rolling if she used a wide stitching pattern.
