As you study case making you will find that there isn't much that you can do that hasn't been done before in some form or another.
Recessed cavities are common in case making. "Hidden" pockets have also been done by Instroke, New York Case and Murnak and even Predator has a version. Me and Allan McCarty designed a case like this on paper 15 years ago.
Backpack straps - Talisman, Murnak, JB Cases, Sterling Wave cases.
Folded over leather with rivets along the side - Justis
Slip on tops with snaps - Jim Walker Cases
I have well over 1000 pictures of cue cases and various cases for other uses. The range of creativity in making cases is quite diverse.
I have the feeling that you are one of those people that will push the envelope on how to build cases. I look forward to it as seeing new ways to do things is what really fascinates me.
