This video inspired me to suggest a session for the USITT National Conference. We called it "Analog Sketching for the TD." It shows the drawing of a cleve, from start to finish, using markers. One of the keys to the artist's process is turning the paper while s/he draws. One particular technique I've picked up is using a finger to help guide the pen during shading. The finger works as a stopper of sorts.

"Keep away from those who try to belittle your ambitions.
Small people always do that, but the really great
make you believe that you too can become great."
— Mark Twain
Drawing: You can do a drawing on
almost any smooth flat surface. Be sure the surface is clean. Any
debris under the paper will cause your pencil to leave dirty marks. Yuk.
Drafting: For drafting, you're going to want a surface that has a straight edge along one side. If your right handed, you'll want the straight edge to be on the left. If you're left handed, you'll want the straight edge on the right. I know, duh.
