I've noticed a number of ceremony photos that have the aisle ends of the rows of chairs/pews 'roped off' with tulle as well as the aisle itself. Some of them have aisle runners which I understand is only for the bride and her escort.
I've not been to a wedding where this is done. I'm curious as to why. Do guests get seated from the other end of the rows? How do parents of the bride/groom get to the front rows?
