Heather at Notes from lapland come up with the idea of a kind of pen-pal thing, well it is a post club, once a month you get details of someone to send something (anything) to.
Anyway heather does the club better than I could here.
I decided that it is lovely to send and receive something, in fact I love the feeling of anticipation when I know the postman will have a parcel for me and I also love the fact that it doesn't have to cost a lot, so I signed up.
