We've talked about this before, but I'd like to see all the different ways Philofaxy readers use their Filofaxes beyond diaries and contacts.
For example, I use my personal Domino as my Scotland travel Filofax. Yvotchka uses her gorgeous slimline Amazona as her Financial Filofax to keep track of expenses and bills (love this!). I know Steve uses his Slimline as a wallet.
What other uses do you have for your Filofaxes?
