I got the pdf and I guess I was expecting more. It does what it says and shows you how to make
various shadows but that's it. No real explanation or insight into routines or other props you may
need or want to use. There is another of these that may have more info, but surprised this did not
have any of it. Just ok. Buy something else that is more useful like a pull. Thumbtip, or a deck of
cards.
