Step 1: The initial plotting
The first thing I needed to do was decide how big I wanted to make the board, so I could plot out how big to make the pieces and such. I was trying to decide between having each square be 1.5" and 1.25" to a side - the red outline in the picture would, of course, be for the 1.5" squares. I'm pretty proud of how I did this (graph paper is your friend, folks!), especially with the overlapping and such.
