Step 3: Cut out the pieces
Warning: Cutting out paper can be very dangerous! Be sure to ask your parent's permission before attempting such a dangerous task, even if you are above the age of 20. Hell, even I still do it sometimes.
"Hey Dad, can I cut out this papercraft?"
"No Son, cutting paper ruins lives. It's what made your old man go insane and become a cat hoarder!"
"But I always thought it was because you didn't wear any pants!"
"Yes, that too."
