An album side is like a page in a book. If you were to hold up one page of a book, you would be holding two sides, the front and back side. The same concept applies to your wedding album. For this reason, sides must be thought of as two sides at a time and cannot be created individually.
Two sides of an album equal a spread. Some designs will be appear on one side at a time, while other designs will span across the spread. Because the albums we create are flush mounted, the pages open flat so the crease is barely visible.
If you elect to add or remove sides from your album, you must do it two at a time.
