Take a piece of paper and fold it.
Now grab a pen and start outlining what goes where.
Follow that as a guide in InDesign.
I have both sides laid out and ready to print. My question is should I have the printer print it head to head or head to foot. How would you have it printed. Is there a proper way?
I thought Bob's answer would handle that.
The "Printer" - A peripheral device for output or a guy who (should) know what he's doing?
Most brochures are Portrait reading. Head to head such that when you unfold everything is right reading as the panels open. If the opened interior is landscape plenty of discussions arise as to which way to rotate; there is no definitive answer.
You might have the outer back panel rotated 90 degrees for address info. The post office would want the tabs at the top when reading, folded edge to the bottom.
