Old Favorites: Post-it Art
One of my favorite things to have done in art is drawing on Post it notes. I think this grew out of my Sketch Card days since the size of the final art is somewhat similar.
These were so much fun to do and an exercise in keeping things simple due to the size constraints. As a digital Artist, having the ability to easily zoom in and out (something that's not done in traditional art), I tend to over analyze things and add more detail than I should. Doing art this small (and even smaller on other occasions which I may share in another post) really helps to simplify things. You find you're not thinking about detail but rather shapes and the more important elements of the image.
