You can get giant prints called "engineer prints" at Staples for $4.99. We called around locally to see what we could find. Our local Kinko's had a similar giant photo copy option called a "blueprint copy". I also heard from a reader that they are sometimes called "draft prints". These prints are only .75 per square foot.
New cheap drinking game my friends and I invented! Hot glue solo cups to a poster board and then make up your own rules! The two cups in the middle on the bottom row are glued away from the poster board by toilet paper rolls to add a higher level of difficulty. Really fun! We call it Wall Ball!
