We have a shop in South Australia called " Cheap as Chips" and I watch out for their cards. I can buy some very cheap cards with excellent photographs of dogs on the front and I use them as my dividers. Yes, I am a dog person :o) They also have some excellent stickers but I am really not a sticker person.
I think you should use the two days per page Filofax fill and then you can do your own decorating. Besides too much space, the Flavia one is already decorated so it's pretty but not so personal. I am using week on two pages Filofax and can get my info on but no room to doodle. You inspire me want to go to two days per page so I have more room but not too much.
I found this really good website for organiser stickers! http://www.organised-mum.co.uk/OM-Stickers.html the pnp only £1.95 also!! x
