I am also having my ceromony on the rooftop . We fell in love with the location. Can u believe they don't have black sashes will have to buy those as well. It's funny because I called my wc and told her that I saw that centerpieces were $40 per table and she was like no that's something you have to talk to me about directly, centerpieces are not $40 per table. Because I was trying to talk her into giving me a better deal. She said she would email me , no response yet. When she does I will keep you posted. And I agree it's no fun stressing! I actually already bought all my centerpieces because I planned on having a celebration in our town and reusing the decor. Good luck to you too!
