Last spring I got fascinated with the filofax, so I tried it out as an agenda. And I watched endless of youtube-videos on people making theirs amazing, but for me it did not really work. The pages were to small and it was hard to write with the big binder. So I thought I tried something different.
I have ordered from before from a page named personal planner where you can design your own planner. Or not the entire planner, but have a custom front and back, inner pager and decide colours and elements inside.
