Regardless, the middle star does not dictate the orientation of the flag. If you prefer to display it with the middle star upright, more power to ya, but that way is not any more correct than any other. Hoist to the left, fly to the right is the only indicator of "up or down" "top or bottom". If you can determine which way any seams were made, generally the "clean" side of a seam is towards the front. But that's being kind of nit-picky and like most everything else about Confederate flags, it's not a hard and fast rule.
