Sorry that I didn't answer earlier, but I think Sue is out of town for the next few days.
Because I made my quilt with scraps, I didn't really pay attention to Sue's cutting chart.
However, I would say that if you have a couple of leftover pieces after you have assembled your blocks, don't worry about them. You can either save them and try to use them later, or toss 'em.
When Sue gets back I'll see if there is more to add.
SEW LONG!
