I'm sure she doesn't sew the finished quilts you see behind her... she has STAFF, including her daughter Natalie, who do loads of that for her. She is showing the method, in the quickest way possible for the video. The pieces you see her sew don't go into an actual quilt. She's just showing you the shortcut methods she's famous for. It's fine for you to take more time than she does to get your accuracy.
