You could go to a beach and find someone just painting stones as a job (Lulworth Cove in Dorset). A respectable way of earning some money as an artist. Sitting in the sunshine, working on imaginative designs. We bought one with a blue octopus painted on it. The stones were probably collected off the shingle beach (yes I’m writing about different shingles). I would love to go back there but I doubt this artist would still be plying his trade. Yes the world has changed.
