Today I had some thoughts rolling around in my head and I wondered, what would it be like to have only A to Z dividers? Monthly pages? They go under M. Weekly pages go under W and future pages just go under F. The printer warranty could be filed under P or W; I would use Giftie's index method (see sidebar) to keep up with it all.
At the very least, I could see myself using this method in a supplemental planner, or an archives planner of sorts. Wild idea - do you think it would work?
