I included some illustrations of card layouts back on page \pageref{cards}. Since these are just rectangles, I knew I could create them pretty easily using the \textsf{tikz} package. All I needed were the coordinates where the three rectangles would begin and end, and the coordinates of the nodes where I would put the letters.
As it turns out, this was difficult to figure out using my mind alone—there was too much guesswork. I'm a big fan of having the right tools to do a job and then using those tools. I see no point in being a martyr. So I pulled out the best tool I had for this: graph paper and a pencil. No guess work, just straight lines and a bit of counting. I felt like I was in my eighth grade geometry class again, and I actually enjoyed it.
