We visited this venue yesterday and are in love. Our colors are black, white and blush...how would you decorate this space? We will ya e the reception in here...the ceremony is in a room that is identical, but narrower with the same center focal point and stained glass.
You can rent from Hobby Lobby items like arches, columns, even candelabra, etc. I would make an aisle with chairs, flowers, and greenery. You could use tulle instead.
On other side, nice tablecloths on tables, chairs, table decor, area for dancing if so inclined. Keep bar/drinks on different side than food, and a table for guest book, gifts, card and favors if any. I would cover canvasses with wedding paper.
