That's not quite what I was saying, but that is how you connect the front and the back together. What I was trying to say was by using letter size paper the pieces might not fit completely on one page, and will have to be printed on two or more sheets. If that is the case, it isn't a big problem, you will just have to cut the pieces out, and then glue them together to make it one piece. It isn't hard or complicated, instead of folding a tab, you just leave it flat on that one section. It will make more sense once you try to put it together.
