I have a bit of a penchant for close up photography, so while husband was playing hide and seek on the beach on a recent camping holiday:
I happened to spot a small stone, firmly wedged in a hole in the groyne (sea defence). So I took a photo of it. Then I spotted another, and another and another, and before I knew it, I had lots of photos of small stones stuck in holes.
There is something rather beautiful about these dull little pebbles, forced by the sea into the holes and wedged there until the next storm takes them on their way.
