Here ill show you a quick Instruction to Build a Psycho Maske out of Paper.
Step 1: Pepakura'n Stuff
First, you need the "Pepakura Viewer"
You can download it on the Original Site: http://www.tamasoft.co.jp/pepakura-en/download/viewer.html
Then go to this Site and Download the .pdo Pepakura from "botman" and open it.
(At this Point, Thanks to Botman)
Step 2: Printing and Cutting
Now print it on heavyweight Paper (it will make your Mask stronger against Mother Nature)
Now THIS is time consuming.
Cut every Piece out.
Step 3: Glue It! (Pepakura Viewer Helps How)
Know you need to Glue the Right Part to its Counterpart.
Open Pepakura Viewer and .pdo again.
If you go over it, a Red Line will show where you need to glue this Part.
This Screenshot should say more then needed...
Step 4: Finish Him!
Just Glue and Glue and Glue it :)
It takes his Final Form! O:
I recommend making little Holes in the Eye Part to see trough it :)
(Botman says the same :D)
