So I went to the bookshelf, and what did I find?
Drawing on the Artist Within by Betty Edwards, Author of Drawing on the Right Side of the Brain.
Well I never. The fact that I own this book, and have not done much more with it than flick through the first couple of chapters seems somewhat ironic, although I can't quite put my finger on why, and definitely have nothing to do with the comments in the original story of this group.
At least I'm not an artist and have no aspirations to be one... ;)
