Loopymumsy, just got my new diary today and have the same problem. At a squeeze and I really mean squeeze, I can just about close the cover but that is without a pen in the holder. That is also without any bits of paper which I always seem to collect along the way
I expect the leather covers would look nice but I found my diary lasted well enough without the extra cover. Mind you, this time I'll go for a more 'professional' colour than pink. Turqoise I thbink is the only other option.
Does anyone know of any other products like this (diaries with many columns)? Thanks.
