Botanical Art Techniques A Comprehensive Guide to Watercolor, Graphite, Colored Pencil, Vellum, Pen and Ink, Egg Tempera, Oils, Printmaking, and More by ; Carol Woodin; Robin A. Jess

 This is a comprehensive guide to the materials and the basics of botanical art with excellent examples and lovely pictures. It even tells you the right way in which to hold the pencil! It is really the kind of reference book that you need to keep in 'hard copy,' however. I love these books, but it can be difficult to use them in ebook form. 

It also has sections by different artists, and provides illustrations of how to draw different flowers, and discusses the parts of flowers.

I received this free ebook from Net Galley in return for an honest review.
