It’s origami. I had a really fun time, making each little piece, from the drawers to the trousers. Of course, the trousers and drawers combo was the center piece for this side quest. And the pants do fit perfectly into the sliding drawers.
I created and posted my own tutorial down below on how to fold an origami trouser so that you guys can all learn how to extraordinarily fold paper pants during this time. Hopefully, origami will be a nice hobby for you to start with.
