Hi everyone!
Since drawing is often the basis for a good painting and we can never have too much drawing practice, you might find these lessons very helpful:
At artacademy.com they're currently offering a 7-part Workshop on Drawing Drapery.
The lesson announcements are delivered in e-mail and you just click a link in the e-mail to go to the page at artacademy.com where you can download the lesson PDF file. The PDF contains advertising since artacademy.com also sells DVDs, Books, and other products but the free drawing lessons are more than worth the advertising. Besides, you may decide to buy some of their products once you try the drawing lessons for a while!
I've subscribed to the free drawing lessons for several months now and find them to be quite good, covering many subjects and artists' styles.
Hope you enjoy the lessons and show us what you've learned!
