Read and look at Mona Brookes book, Drawing with Children. You'll be amazed
and inspired and convinced that children can draw still life....with values.
I think it's one of the most amazing books I have ever read and have used the
techniques from it in classes that were from the most deprived areas of
Memphis, with children as young as Kindergarten and saw them draw beautiful
flowers and birds. It really is a "doable" book.
