Part 3 of our What's in your Filofax? series is about the plethora of accessories you can add into your Filofax. Maps, envelopes, even non-Filofax ones (the ultra-handy Swing Pad by FC comes to mind).
In my long-term Filofax (which is my Personal Deco) I keep:
Clear page marker/ rulers in my Monthly and Weekly pages
Sticky Notes accessory
Maps: International, Europe (which is so old it still has Yugoslavia), and Scotland (from the Filofax British Isles maps)
DayRunner calculator that I've had since 1995 which I love because it can face left or right on the rings (click here to see a photo)
Business card holder
Clear top-opening envelope
What accessories do you keep in your Filofax?
