Paper can be such a huge source of inspiration, I recently came across some pictures of a wedding where one massive and ridiculously beautiful chandelier had been made using these paper lanterns.
It created a fantastic focal point, the reception was held in an old cathedral-ceilinged hall, similar to the picture they used white, pink, yellow, orange and red as there colours. You could easily adapt this idea to your venue.

Paper chandeliers of tissue orbs stapled to narrow ribbon and hung from the ceiling will elicit oohs and aahs from your guests and maybe even a few delighted squeals -- the perfect, soundtrack for your big day.
