Amy & Diana told us about them after last years cruise and Amy organized the swap. A circle journal is a small scrapbook that gets passed around to a circle of friends. You start out your own book by doing the intro, sign-in pages, theme instructions and the first spread. Then it goes round robin to everyone else in the group to do a spread in your theme (last year for example a number of us did Magical Memories or a take-off on that theme). When you get it back you have a book filled with great pages and memories done by your friends.
The SSMC05 circle journal exchange will be done at the Saturday DIS meet. I think I can speak for everyone involved in saying we had a great time with it and we look forward to doing one for SSMC06 with even more friends involved.
