We haven’t linked to any tutorials in a while, so here’s another one:  Rendering a red motorcycle on a piece of chipboard (this is the backing material you normally find on vellum pads or newsprint pads).  Most of these end up in the trash, but they’re surprisingly fun to sketch on.  Very absorbent, and smooth — almost like Masonite.  Click on the image above for the full process.  This tutorial is one of twenty that will be featured in the upcoming book, Old School Viscom: 20 Renderings in 20 Steps.
