I mostly do business with clients in the same country as me, so it's no hassle to include the people I've enjoyed doing business with this year in the christmas-card-writing routine. I'm mildly alarmed that this activity might qualify as "marketing" which somehow rings of ridiculous, contrived inventions by people employed entirely to miss the point! Hopefully it's not too corporate though, it's been a good year and I quite like to keep in touch with people.
So - it's that time of year and I'm off to fill my fountain pen and sit down to write those cards ... I did indulge in some tiny lornajane-branded stickers though, to save having to lick the envelopes :)
