Darcy at ART and SOLE is sponsoring a 52 week postcard challenge for the year 2012. This post tells all about it and this post has the links for Facebook and Flicker groups.
It has been a while since I participated in anything like this......Oh wait, I don't think I ever have. Anyway, I think it will be great fun. I'm going to try my best to play catch up for a couple of weeks.
