We get a generic batch of diaries at work. Which for my boss and I means that we are constantly trying to abscond with each others diaries. I found a half used sticker sheet in my desk drawer today and did some decorating. The stickers were from a newsagent somewhere and the pens are Moonlight something from Japan - I've seen the same ones on the jet pen website. I'm not sure how well either the stickers or the pens will hold up but for now it is cute and distinctive.
