Kaonashi, or "No Face", is a spirit from the animated movie "Spirited Away" (2001), written and directed by Hayao Miyazaki and animated by Studio Ghibli. The film became the highest grossing film in Japanese history and won an Academy Award for Best Animated Features. It has since been made into a film comic series.

(SPOILER ALERT!!!)

In the story, Kaonashi started off as more or less a blank sheet. After feeding on people's greed, desires, personalities, and eventually, their physical being (makes a great Halloween story!), it became a gluttonous, self-absorbed monster. He/She/It took an interest in the main charater--a girl named Chihiro--who's family was moving to their new home when they took a wrong turn and stumbled into this world of spirits; Chihiro had to be independent and adapt to the new environment quickly in order to save her parents. After following Chihiro around and meeting some kindhearted people, Kaonashi gradually calmed down and decided to stay with a gentle witch and be her apprentice.

For this projects, I want to portray Kaonashi's initial appearance as the curious, wandering spirit.

Supplies

1 or 2 large, black garbage bags
2 sheets of legal size (8.5" x 11") printer paper
1 sheet of white cardboard paper
1 pairs of scissors
1 utility knife
1 black marker
1 purple marker
1 roll of wide, transparent tape

Step 1: Step 1: Prepare the Cape

Get a large, black garbage bag.
Without opening it, hold the bag up vertically to check if it is sufficient length for the intended wearer. If it is, then skip to #4 below; if it isn't, then move on to #3 below.
Take another one of the same garbage bag, cut the sealed side open all the way with scissors, and attach it to the open side of the first garbage bag with wide, transparent tape (or if you don't have transparent tape, then you could also use non-transparent tape to attach the two bags on the inside).
Pinch and cut with scissors a hole for the face when the wearer wears the cape over their head. Be sure not to cut too much as we want to leave some edge to attach the mask that we will prepare in the next step. I recommend the size of the hole to be big enough to fit most of the face (including eyes, nose, and mouth), and leave at least 1.5 in for mask attachment.

Step 2: Step 2: Prepare the Mask

Get a piece of legal size printer paper that is a couple of inches longer and wider than your head. For the purpose of this instructable, I'm using a legal size paper (8.5" x 11").
Draw the markings, eyes, and mouth of no face based on the reference picture at the beginning. You can make it have any expression, so be creative! Use the black and purple markers to color the markings, eyes, and mouth.
Glue it over the piece of cardboard paper of the same size.
Use the utility knife to cut out the places for the eyes and mouth.
Make two cuts, approximately 2" long each, with a pair of scissors at the top short edge of the paper and two cuts at the bottom edge. The top cuts should be approximately 2.25"-2.5" from the closest long edge, and the bottom cuts should be approximately 2.5"-2.75" from the closest long edge (see attached picture for details). Note that the scales are just for reference--feel free to adjust them proportionally as needed.
At the places where the top cuts are made, pull the areas to the left of the left cut and the area to the right of the right cut in so that they overlap partially with the area between the top cuts. Use tape to hold them in place.
Repeat step 6 for the bottom cuts.
Trim the outer edge of the mask to make it more oval-shaped.
You're done with the mask!

Step 3: Step 3: Combine Mask and Cape

In the last step, just tape the mask over the hole previously cut on the cape for the face. If you want the tape to be hidden, then tape it on from the inside. And voilà! You have a no face costume!

Happy Halloween!
