Since I started teaching origami too many times I have heard it said ... "too hard for me" or ... "it takes too much patience" and also ... "I do not there could never succeed" In fact, with very few exceptions (severe mutilation or other very special problems), everybody is certainly able to fold a sheet of paper. Instead groped to respond to those objections arguing, it is often better to offer a piece of paper and ask to make a bend. Done? Great! This is all that is required to origamista. Nothing but folding paper.
