It was John Ruskin who said that however closely we look, we can never see all there is to see. Even with a microscope there will be more. So we have to make do with approximations. My drawings of Queen Anne’s lace were hardly accurate(it likes to wave in the breeze for a start), but the vase I decorated from these drawings looks reasonably convincing. Recognisable at least. And there are always chances to try again.
