Actually, you have to bring your own supplies, too -- paints, palettes, a chisel, whatever; the DASL invites people to use the model for whatever medium they wish. Monday's open-studio sessions are generally "long pose," meaning the model holds one pose for the session's entire three-hour length. Which is pretty impressive on its own.
The session starts tonight at 6:30 p.m. and lasts until 9:30 p.m.; it's free and open to anyone, but space is limited, so you should probably show up a little early. In the meantime, have a sandwich -- turns out you can afford one today.
