I made a hat like Louise's from Bob's Burgers for Halloween. I love Louise and her evil plans. She is my favorite cartoon character right now, which is saying a lot because I really like cartoons.
Unfortunately, I did not make it out this year, so I will have to think of something else fun to do with my bunny-ear hat.
I made the hat out of pink flannel and used wire to make the ears stand up. I also added a couple of wig clips so it wouldn't fall off.
It also reminds me of Gummo, so that's a plus - maybe a 2 in 1 costume piece?
