Putting prototypes to scale

My head is about to explode. I've been doing so much math on Illustrator, trying to plan out my cuts on the 4'x8' piece of cardboard, that I'm starting to think this is going to be a lot more work than I anticipated. However, if I don't plan my cuts, I could easily spend more money on cardboard that I would like.
Then it occurred to me: if I make general circle templates (since a lot of the diameters correspond to different sections in the chair) I can use those to help create my pieces. I'm hoping this will make the math in my head a little easier.

Also, Margie had requested that we post a photo of our significant other, since so many of us focused our relationship representing duality on a boyfriend/girlfriend.

Here's a photo of Justin and me when we went to an Oklahoma City Thunder game.

And here's a photo of us after a kickball game this summer! Note the different jerseys :)
