For my card, I used blue and gold paper from DCWV. It was a pack of papers with colors that coordinate with the US Marine Corps. The blue and gold matched the graduate's school colors perfectly!
The congratulations background paper is just plain cream colored cardstock that I stamped 'congratulations' all over.
Cricut cartridges used include Locker Talk (cap) and Varsity (2010). I used my Gypsy to weld 'class of' using the Holiday Cakes cartridge.
