I do quite a bit now when I do my pep work since I have learned that unfolds may not always be the best and the slightest "boo-boo" can cause a pep to not line up properly.
► Download pep pieces. (I make sure I have all the required pieces for a costume)
► Load whatever piece I feel starting on. (sometimes I like to do the smaller pieces first since they are usually quicker for me to get done)
► Scale my piece and check other dimensions and compare it to my body to ensure that measurements seem okay for everything.
► If I don't like the current unfold, I will work on doing it my own way and make sure there are no overlapping pieces. I will also make it a smooth unfold if not already done.
► Place pieces so that I have the least amount of pages as possible.
► Print.
►Then I just pick a page, cut, score and glue as I go.
It can sometimes take me about an hour before I finally print out the piece and actually start working on it. In RARE cases, if I feel the need to tweak the model, I will open it in blender first, edit the model to my liking, then open it in pepakura and make it into a smooth unfold.
