It's easy!  Just download the artwork pages and the monthly grids.  Tape each month's artwork and grid together, trim the edges, and either tape or spiral bind the top.
     You can print out each page on a standard printer and then tape the artwork and the grid together to form the finished calendar which measures 10 x 16 inches after you trim the edges.  All of the artwork and grids are in portrait mode (this is the standard printer mode).  You may want to read the Help with Printing file first for some hints.
      Print a calendar for the 2008-2009 school year using the last 7 months of my 2008 calendar and the first 6 months of my 2009 calendar.

       I'll be adding the rest of the months for 2009 this fall.
