I decided to be Fionna the human (the genderbent Finn from “Adventure Time”) for Halloween. I love the show, Finn is one of my three fictional characters and the costume is easy to put together – mostly just bought pieces. However, I did need to make the bunny hat. It was super easy and a lot of fun. So if you’re planning to make the hat (whether it’s Finn’s or Fionna’s), check out what I did.
