as harsh as it sounds... :]
really? you harsh? noooo....
I am actually bummed you didn't put a snarky comment here, as you did for me... crying tears here...
So naota, both jayone and u513 are correct , snarky comment aside
lurking has benefits, read and watch what you can. There is a wealth of information that is available in the stickies as well as reading personal wips and builds.
My advice is to jump in. take an easy build, jayone is right, helmets tend to be more intense, (yet soooo much fun) so plan on something like a shoulder or shin... don't go too small because seriously will kill your desire. case in point skyrim daedric gauntlets.. those fingers are horrendous.... The smaller the pieces the more intricate and harder it becomes. That's true for the more angles and curves and small parts on a large piece.
In my own humble experience, I love the build of a pep, I can build pep all day long. cardstock and my Loctite glue and I'm happy. It helps that I have a silhouette that cuts them out (suuuccch a pain cutting small paper pieces LOL) and I enjoy this part of the build more than any thing else.
I did do a foam helmet (batman cowl) and while it was ok, I loved the pep one better. it's quicker for me, easier... I am not a foam fan overly much because I haven't worked too well with it. The foam helmet had to be redone (harbor freight floor mats) because it was too thick. Michaels craft foam is too thin. Thanks to a group of people here who met up in San Jose, I got valuable information and found a pretty nice eva foam at sears... That being said, I hate how I cannot manipulate the foam as well as the paper.
So, here's your challenge.... What is the character you want? grab a piece off it and show us your pep... walk us thru your thoughts and pics as you build it. Then try it in foam. Do the same. By experimenting and posting it, people will be able to give you tips on how to make them easier, what else you can do, or congratulate you on how well you are doing.
you tell us... which one is better? there are some amazing people out there with amazing skills... some foam, some pep, some freehand... some sadly all three (those people I am jealous of)
a wise and very snarky man once told me to post.....

put it up for us to see, it really does help
