Like most artists, shopping trips for something, anything, involve keeping an eye out for objects that have potential for compositions. Last weekend I found some glass heads and I couldn't resist one for the studio classroom. There were several colour available, including bottle green and cobalt blue but I liked this one that was almost clear with a hint of turquoise in it.
Of course I had to play around with a quick sketch of the head using pen and watercolour wash in a totally unsuitable sketchbook that ripples with the moisture. But that's fine. My sketchbooks are working tools, not designed to be works of art in their own right.
I'll be setting up some compositions with the head to find just the right one to do some drawing and painting with it.
