Right Angle Half Fold
A right angle half fold is created when an 11x17 sheet is
folded in half to 8.5x11 and then in half again to 8.5x5.5 thus
creating a type of book or pamphlet that can be opened to a
full sheet of paper.
You will often see this type of fold used in the print media
that goes with CD's, DVD's, or video games. Information will be
presented on the outside panels and when opened will reveal a
poster or artwork.
