A friend of mine introduced me to Gravity Falls. Thank God he did, cause it helped me ask him out
Here's his answer~ [link]
Sorry about the cruddy quality. Right when I finished it and printed two copies, Adobe Illustrator crashed and I hadn't saved at all, so this is a scan of the original copy. I'm planning on remaking it so it can be used by others or something.
I don't own the design! I traced it from Gravity Falls screenshots! Credit belongs to the people that did the art for the show
Edit: Here's the updated version hot off the Adobe Illustrator press! Hopefully, this one looks cleaner. I made it transparent so that hopefully it can be printed on any paper in a way that looks nice and clean. Girls, use it if you want.
