I have discovered that I rather like sketching open books. I like these quick sketches, they are opening my eyes to the things I like and the things I don't like.
When you think of taking a leaf out of someone else's book it's because you think they have got things right, so you want to emulate it. Trouble with me is I am very independent and stubborn which means I cannot take a leaf out of anybody else's book, because I'm too busy writing my own! I like the saying all the same.
