Yes, it's true, Sandra Goldmark is the bomb. She's a tough cookie, and you may be frightened by her uncanny ability to look at your work and know how you were feeling when you created it as well as exactly how much effort you put into it, but face the fear and DO IT ANYWAY, as that one book says. She's absolutely brilliant, very talented, quite straightforward, and a great human being to know (and admire... as you surely will). She invests in her students when they invest in their work.
This is essentially an art class, which is both frustrating and exciting for non-artists. You'll do a combination of dramatic lit analysis and rendering projects, including basic workshops on watercolor and color theory. What you're able to pull off in terms of design work has less to do with your talent as a painter or sketcher and more to do with your ability to form and communicate concrete, well-justified ideas about costuming each piece. It DOES help to have a background in visual arts. You MAY feel downtrodden if you can't draw to begin with, and she isn't going to hold your hand while you figure out how to negotiate that. However, Sandra is a genuinely caring and understanding person, and if she thinks it's fair, she'll cut you some slack. Only if she thinks it's fair. Otherwise, like I said...tough cookie.
The class includes awesome field trips to costume shops, an opportunity to build some stuff, and frequent class-wide critiques of your work (which is less scary than it sounds, and once you get over the initial shock of opening up your artsy brain to honest peer/prof critique, you'll find yourself reaching out for as much as you can get).
Be prepared to spend some money on supplies and printing! This is a pain, and you have to do it.
This class opened up a whole design world to me, and I looked forward to it every week. It's not easy, but if you work hard and come to class prepared you can expect to feel refreshed by the creativity of the work and proud of what you accomplish in 15 classes.
