Add a hex sticker

@ekothe wants a hex sticker.
I think @djnavarro could make a badass hex sticker for this project if she was interested.

@djnavarro - absolutely no pressure if you're not interested, but thought we'd tag you in case you are ❤️ 🏳️‍🌈

I'm interested 😁 I'll see what I can come up with once teaching calms down!
