If you want to do pepakura you need to take a few things into consideration.
[]Cost (like any costume, it'll cost a lot of money to make a full suit of pep armor)
[]Health (you will want to buy the proper equipment to keep yourself from harming yourself permanently)
[]Determination: (Pepakura like any great hobby takes a lot of time to do)
[] Environment: (you will need an area outside to work with (yard, open garage) and will need a warm temperature (winter isn't the time for it))
If you still want to continue to do this (and I hope you do, I didn't want to discourage you.) I can send you some files that I have (I haven't made them, but I have downloaded them), as well as point you in the right direction of what you will need. Just let me know.
