Carla Sonheim, in the children's section of the library. I took it home and got lost in it. The message: inspiration can be found in everything. Combined with simple techniques to get you going in the drawing field. Our daughters are more into other things than drawing these days, so I had the book all for me. Some cute imaginary animals (title of one of her other books) resulted from the 'cracks as inspiration'-chapter. I really hadn't been drawing for fun for years, but I love it! Have a look at the tutorials on Carla's blog to start drawing and painting.
