So I have just signed up for yet another swap - this time it is ART IN A CARTON. What is is? - well "Art In A Carton" is essentially a three-for-three swap. It's an artsy little "Pay It Forward" idea dreamed up by Susan of Art Angelix. She will send a carton of goodies to me, I then a) send her something back in a decorated carton and b) send another one on to two other participants - the package coming to me will have address labels, I send out to the oldest address label and a person of my choice.
