Also i will be making the rest of the costume on a separate instructable
Step 1: What You Will Need
white baking Flower
Unused paint brush
Clear spray paint
Step 2: Pepakura
After opening Pepakura, open the obito layout you downloaded. From there measure the height of your head and scale it to the software
(there are all kinds of videos on the internet about how to scale your mask but so you know get a measuring tape and measure the top of your head to your chin in millimetres. My head height was 290 mm)
When thats done print it out and trace it on to the card board you have
Step 3: Puting Together the Cardboard Pieces
Step 4: Paper Mache
Using the paint brush i wet the cardboard mask surface then added a piece of knews paper and brushed it again with paper mache solution.
I added 4 layers of paper mache onto the cardboard mask. Also i let it dry completely before adding another layers but i was told you can have up to 3 layers at a time.
Dont forget to paper mache the inside of the mask. I only put one layer because i got lazy.
Step 5: Paper Mache Pulp
To make paper mache pulp I tore toilet paper into small pieces, boiled some water and continuously stirred it untill it broke down to even smaller pieces.
From there drain the toilet paper, add glue and flower (i didnt use alot of flower) untill it turns to a paste texture.
Apply that to the mask. My paper mache pulp took 2 days to fully dry.
Step 6: Wood Filler
After the wood filler had dried i sanded it down for a smooth finish. First i used 80 grit sand paper then moved down to 120 grit sand paper.
Note: do not sand past the base of paper mache pulp. Your only trying to fill in the cracks and dents
I also used a Dremel to sand off the eye wholes for a nice round finish. You dont have to do this but i wanted the roundness to be perfect.
Step 7: Painting
Next i drew the circles to represent the Rinnegan. To make the circles as perfect as i could get them i taped the Pepakura paper printouts to the mask then traced them one at a time
Fill in your pencil drawings with black acrylic paint and let dry.
Step 8: Clear Spray Paint
When it is dry it should have a nice shine to it.
Step 9: Finishing Touches
I also cut a strip from a baby blue shirt for a head band. The last few pictures show how i put it together
I put on the black sleeve first. Then tied the blue headband on like a ninja turtle. Then i put the helmet on last.
