The joy of Filofax is the customization. You choose the binder, and everything that goes into it. Every single thing you put into your Filofax, or not, is your choice. It's glorious.
Here on Philofaxy we talk a lot about calendar insert formats, tabbed sections, etc. But let's talk about what else you keep in your Filofax.
I think Filofax has done a pretty good job of offering accessories to go into the binders, but of course there could always be a larger selection.
In my Filofax(es) I like to have maps of anything relevant (and I wish they would expand their map selection to include more city maps, and PLEASE an updated map of Europe!). I use the Sticky Notes accessory in every Filofax I own, it is so handy to have. I love the stickers, and even better that they are on a page that fits on the rings. I keep stamps in the zip pocket. I use the Business Card holder pages to keep cards in the back of my binder. I also use the clear pockets that fit on the rings to hold ticket stubs and maybe a photo.
Things I don't keep in my Filofax are money and cards. I keep those in my wallet. It would be too fiddly for me to sift through all my papers and random scraps in my Filofax at a checkout. I also don't have a portable hole punch, although I know many people do, and I think it would be very handy.
What do you keep in your Filofax? What DON'T you keep in it? And, what accessories do you wish Filofax would add to their selection?
