I'm always embarrassed when I accidentally write something on a Netflix envelope, like some Netflix employee is going to automatically know I'm a weirdo from my scribbles. Not if I had these envelopes though, they actually have impressive art on them.
Apparently, there are a ton of people who sketch over Netflix envelopes and they're all pretty good. I especially love when they incorporate bar codes and panels within their drawings. Like ho ho you clever bastard! The next level: use the Netflix envelope to draw a picture depicting the movie you just watched.
