This pocket-sized red patent Filofax belongs to one of my students. She has been using it for about a year now and finds it extremely useful. I love pocket size because it is not too big, not too small, and many Filofax binders in these size have full length wallet pockets, even if the larger sizes do not.
Liselotte loves the accessories you can get from Filofax, like Post Its. Here she is showing me her fold-out year calendar and how useful it is. You can see she uses the Post-Its to be able to quickly find and flip to something.
