I like a whole lot of mediums, but my absolute favorite is the humble drawing. If pressed, I'd say pen on paper is my preferred category.

I love how one can take the simplest of materials and create a window into an abstracted reality. It's a raw medium, where it's hard to undo what is already there, so one has to either incorporate errors into the final piece or avoid them entirely.

So what is your favorite medium for visual art? Have you attempted it yourself?
