This is hideous.  I would like to make it like yours Miss Nancy, but with much narrower planks.  Can you show me a little more.  I'm still a bit niave as far as the materials go ... I don't "get" some of the more math oriented features.  This was from scratch, using the brick node and plugging in the wood for the bricks.  I added specular and reflection.
