Reader Stories: Art Questions Answered by the Art Agony Aunt

Have you got an art question you need answered? The Art Agony Aunt may be able to help. While I don't have answers to absolutely everything, if I can help I will. (Though answers to art homework assignments you are supposed to hunt down yourself and requests for art critiques should be posted on the Painting Forum.) First though, use the Search box at the top right of a page to check your question hasn't already been answered, or browse through the Painting Q&A.
