Sometimes I think I would just like to have a few sketchbooks and pencils and just draw nature and I'd be as happy as doing anything else. There is so much to learn and see in nature to keep one's mind busy ...and challenged! This is a book I have that I still enjoy reading. When I see it, it reminds me that I should be drawing from nature everyday! What about you, do you have a favorite book that you could never part with?
