In my Materials and Techniques class, we did something that is fun, and a bit nerve racking, ink drawing. No pencils first, just using ink as a drawing medium. I found a bunch of random photos online and had them draw what they saw. I also forced them to use specific inking mediums, and some were a bit unusual. Below is what I came up with.
Above was drawn with a stick (like, from tree) and a pink towel someone left in my room.
