How fun would it be to have the only black house in the neighborhood; nay - the entire world! Nobody thinks to have a black house. That's something only found in story books about friendly witches. It would remind me of Miss Piggle Wiggle. She had the only all brown and upside down house in the world where all the interesting & problematic children went.
This is what I've been painting on. The paper is heavy, has a nice texture and solid color backgrounds.
