Karen emailed me a PDF file with a few pictures of different arches used to decorate crescent terrace when I was still deciding. In the end I decided that I didn't like any of the arches so I opted to rent 2 of the white pedestals and put flower arrangements on them. We're lining the aisle with rose petals and hanging pomander balls from the chairs. I think crescent terrace is really pretty already so it doesn't need too much.
If you want me to send you a copy of the PDF file that Karen sent just message me your email address and I'll send it over.
