I'm planning to be Finn for Fanime this year and so I got some stuff.
How I got my hands on the stuff:
-Hat- I skinned an evil bear and got Jake to taylor it for me. ([link]
-Backpack- I recently got it shipped in from the Grass Kingdom. ([link]
-Enchiridion- Simon recently discovered it so I decided to break in his house and go get it. (Cardboard+Acrylic paint+yarn+encouragement to do it=Enchiridion.)
