Folding a parallel line

Assume that you have been given a piece of paper containing a straight line and a point not on that straight line.  Figure out how to create a straight line through the point that is parallel to the original line, using only paper folding.  Make sure that your method doesn't require any estimation on the part of the person doing the folding.  Write up your method in a series of steps that someone else could follow.
