a couple of the techniques on how to do this type of cool paper that Marisa made. 
1) How to make the different, slanted shapes that make up the 12x12 background &
2) How to make the hand drawn pen sketched looking lines around the edge of each section.
Marisa: If you ever felt like it {hint, hint} I wouldn't mind a set of these types of background templates. 
It looks like these were created in Illustrator, am I right?
