This is a really-basic paperman that goes arround me from the last 25 years.
I did it lots of changes, now it is a lot more complex, it can hold banners with messages (I always had one telling something, sitting on my computer's screen at work) and looks a lot more human, but this is the basics you can start with.
Just 13 cuts on the paper, and 10 creases, and it stand of its own or sits as a person.
It becames better with smooth shoulders (cut them quarter a square in diagonal) and with the head slightly tilted, but it means two more cuts and one more bend and now I'm talking about minimuns. May be other day.
I hope it makes you smile! Thanks for your time!
