Yes, the 6-1/2" cut on diagonal is really my question. I just emailed the class instructor to get clarification. All I have is a simple cutting list and I'm not sure if she is using the words" cut on diagonal" and "cut in half on diagonal" interchangeably. Thanks for helping me understand the I need to ask the teacher. :-) The class is in a few weeks from now, so I have time to wait for a reply before cutting. :-)
