This is not etiquette related, but this board always seems to be the most active, so I am hoping that someone here can help.
We are having approximately 200 guests, which I think will be about 13-15 rows of seats. Any idea how many rose petals we will need? Most information I have found gives estimates by sq ft. I am thinking that 15 rows of seats will be about 45 feet (times 2 sides) but really I have no idea. Anyone have any experience with this?
