Patterns at my feet

Whilst walking on the seashore last week, looking for anything unusual that might have been left behind by the ebbing tide, I became increasingly attracted to the pebbles themselves.  In fact, it was a shingle beach so the pebbles were very small  –  the largest not more than 3cms across  –  and yet the variety of shapes, colours, textures and patterns was fascinating.  How easy it is to overlook the familiar!
