I ordered the Personal Songbird as I found it on Viking at a very low price. This is just a start, as I want to make sure that I do use it and that it would be worth the money. I would eventually like to buy a nice leather one, but those are too expensive right now, for a first Filofax.
Anyway, I am very happy with it so far! It’s pretty, and I think Personal is the perfect size. I would maybe get an A5, but I don’t think I could go smaller.
