I'm not sure why I always feel like apologizing when I indulge in some shameless self promotion. I think it's because, like many other designers, I'm really not comfortable selling my own product. But, on the other hand, there are only 16 days left until Christmas which means 16 days left to get yourself the Cartolina Holiday app and send all your friends and other favourite folk a pretty little Cartogram. I send out lots of holiday cards at this time of the year but this year I'm going to also use Cartograms to send casual greetings and invitations. I've received so many Cartograms from my bloggy friends and my Twitter pals - it's wonderful. Even though I designed them I still love to receive them in my inbox! So why not send something pretty hi-tech this year - or even better, why not gift an app from Apple?
