Book excerpt: An imaginative compendium of ideas to delight readers and dispel boredom. Discover how to doodle a sloth, turn pencil shavings into pictures and draw in ways you never imagined. Then try printing, spattering paints and painting with dots. There are ideas for portraits, patterns, optical illusions and more, so you'll soon have enough artworks for your own exhibition -- and this book will show you how to stage one too.
