This is for a fan edit of Star Wars. Printing this one is a little more complicated.

For the larger version, save both pieces to your computer. Load up one of them in your printing program...I just use Windows Paint. Adjust the margins and orientation so that it is perfectly centered on the page in all directions. Print. Load the other piece and print it on the other side of the same sheet of paper.

To check if you did it correctly, hold it up to a light or window. You shouldn't be able to see any of the image through the page - they should be perfectly overlapped.

Cut out and fold in half.

For the smaller ones, you can just print them out individually or use the method above to print them back to back.
