Mainly, I have been buying stationary.
Don't let anyone tell you that's not fun.
And I'm not even talking about the cute, colourful and horrendously over-priced stationary in kitsch little gift shops and Paperchase, which some people quite commonly fawn over. Actually, I never get why people fawn over polka-dotted notepads. I prefer my stationary to be sturdy, business-like, practical. A light-weight folder with clamps for added versatility (you don't need to hole-punch!) is more the sort of thing that gets me excited.
Come on, you have to admit it's a genius idea. If I weren't sorted for folders for life by now, I would have bought one of these in every colour.
And there's something so fun about organising everything just so. Organisation can be very pretty too.
