I set myself the task of looking for letters on the beach. My self imposed rule was that I wasn't allowed to move anything or rearrange - it was just what I could see. In hindsight a foolish rule was that I also didn't write down which letters I'd done - consequently several beautiful photos had to go, as they were repeats, and of course there are some gaps.
Kept me amused for a-g-e-s! And it's a nice reminder that the sun shone quite a bit while we were away too.
