Our ceremony & reception are at a private home and I've already met with my 'day of' planner with whom I have discussed the possibility of needing to tent if there is rain... but what if it's just *cold*? We are already planning on renting heaters, but the tables will be in the backyard on grass, and we live in Southern California... so it may be temperate, in the 60's or it could get to a chilly low 50's into the evening. I was thinking of getting some sort of canopy for the seating area (it is only about 30 guests) that we could light and that would also help contain the heat of the heaters but couldn't find anything to show this in photos. Anyone have a resource for this sort of thing that I could show my planner and the rental company we plan to use? Thanks!
