Designer Shells

She sells sea shells on the sea shore,
If she sells sea shells ..................


Help!    I can't remember any more!   

I came across this on my walk this morning, we had gone a slightly different route.   It is in someone's driveway, the part between the paving slabs, which is usually filled with gravel.   It was the full length of the drive and there are about three of the centre shell patterns, but I decided on this shot as it showed the detail of the mosaic.   

I think it is a brilliant idea and must have taken some time to complete.
