When you get your planner just the way that you want it, feel free to print out this cover.  Based on how my planner worked, if you plan on binding your planner, I recommend printing the covers on card stock and getting them laminated in 10 mm lamination.  If you trim the top and bottom of the lamination the extra plastic can serve as a guard and the left side.  The strength from the 10 mm lamination keeps the card stock rigid.  It works great!
