This is a quick guide drawing drapery.
It explains drapery simply, clearly and then goes on to provide many examples which are based off that foundation knowledge, applicable to any situation. The examples are drawings with the body line art underneath to show how they hang and interact with the body.
It's a thin and effective book at 48 pages.
