Typography is about the details, and poorly displaying your work can obscure these details.
Your work should always be...
Tacked down at all four corners
Printed on clean, flat, unwrinkled paper.
The work should be hung straight and level, with the bottom edge parallel to the floor. Each page you hang on the wall should have 1" of space around the design...crowding two works together turns them into one.
Neatness
Cleanliness
Visibility
Reverence
Respect
