My friends have been telling me now for some time to get the book "9 Heads." Well while at the Union Square Barnes&Noble last night I came upon that book and thumbed through it. Excellent! Such a plethora of how to for flats, finishes, figures, garment detail etc. But since I am on a tight budget right now, I was not able to buy it, instead I copied some of the garment detail pictures they had in there. Also, there is a book titled "100 Years of Fashion Illustration" that is also very nice.
