Folding

Tinuviel's comments:
This is basically origami which you can do with parchment from Redcliff
(on Infidian).  There is an NPC there which gives lessons that gives you
some initial ability, and then gives you paper to practice with.  You can
go back for further lessons.  You can 'smooth' or 'unfold' the parchment
to fold it again, though after a few uses it becomes so creased all you
can do is ball it up and throw it at someone.
