I wanted to do something special for our daughters wedding. I displayed wedding/marriage pics from both sides of the family. I had vintage, as well as modern pics. The wedding was a rustic-boho theme in winter, so the display was a wooden pallet, tied to
photo display for a party - double sided so they can spin a little. / you could do these right beside the hanging table. Maybe use streamers in your colors to hang from the exposed trusses to kind of add color and a block from the big empty space.
