The template fits on a standard 8.5x11" piece of printer paper with landscape orientation.
Currently on version zero.
Folding Hint
Fold the paper such that the Post column is at the front, Reply column is at the back, and the Address column is tucked into the center.
With the print out flipped over (text facing down) fold the Reply side edge to the Address side. If the address boxes are visible through the paper, use the inner edge as your guide for the fold.
For the second fold, take the Address side and fold it to the crease you created with the first fold.
Fold over the Reply side. Your post should now have the Post side and Reply side visible, with the Address column tucked into the middle.
