Folder Folding

With the baby wraps, does the cloth need to be folder EXACTLY in half?
I am using my Moby Wrap and just getting the hang of it. Does it need to be folded exactly in half? Also, how to keep it folded in half for next time, so I am not always preparing it every time before I am ready to put it on?
I don't think it matters. Babies wiggle so much that no matter how perfect something is at the start, five minutes later it's wrinkeled and uneven. Ever notice little kids with the seam of their pants so far to the side you think it must hurt?! Good thing they have diapers.
