I feel this belongs in a 'stationery' topic but there doesn't seem to be one...
Every year or two, I buy an A5 notebook with dividers which I always use in the same way with sections for eg. meal planning/shopping lists, projects, to do lists etc. But some sections get used up quickly and others remain half used.
I'd really like to buy an organiser with refills and moveable dividers so I can customise it and not end up wasting paper. The obvious one is Filofax but I don't really like them and they feel a bit clunky / dated. I'm sure there are other options around - recommendations please?
