Anita, I have just come the comforting conclusion that I'll have to paint acres and acres of water color landscapes before I will look for even a passably fair one. After about ten attempts — I certainly have to laugh at myself — It's like feeling around in the dark — thought I knew what I was going to try to do but I find I don't — and guess I'll only find out by slaving away at it. I feel — like a wreck — Have been working like mad all day — and you know how deliciously disgusted with every thing one can be — when the sun begins to go down — and one has been working ones head off all day. It gives me the sensation I used to have when I was a youngster and was going away from home on the train — It is a very special sort of sick feeling.
