There are plenty of designers who "can't draw," but that doesn't mean they can't learn! Artist and art educator Brenda Hoddinott's ever-growing site, Drawspace, is full of free tutorials covering a wide range of subjects, from understanding tone and negative space to drawing realistic hands and feet (and we all know how hard that is). If you're working from the screen it's easy breezy, but the luxury to print out will require you to upgrade your free account. The site is also currently seeking online art instructors if you're not the one in need of lessons.
