In my dream wedding, guests would be sitting on plain brown benches. I love the way the benches are low and don't interfere with the views or the surrounding. I think they are perfect for an outdoor wedding. Unfortunately, they are so hard to find! I was able to find about 35 benches from a rental company in Raleigh, but they were white and 5 hours away.
So I finally resigned myself to actual chairs. I'm sure guests will be much happier and I was able to find wooden chairs so I'm hoping they won't be as noticeable as white ones. We will be using the same chairs for the reception, which makes me excited to think about long rows of wooden chairs with the white tables.
BTW, this last picture comes from this wedding that I am totally obsessed with, they also used haybales as ceremony seating.
