Answer: "B" But with the fabric moving it was hard for me to track. And I measured and found that the size can vary. So I was measuring and trimming every piece which is crazy. I also had trouble seeing the edge but that was before I got my new foot. It might help if you have a quarter inch metal edge to run the fabric along. I'm not a fan of pre-cuts. It must be the frugal in me--I can get more yardage for the price.
