I want to do the "everybody throwing something at the couple" thing, probably birdseed (church has no regulations on what gets thrown, but I haven't decided what I want), right as we leave the church. We aren't doing a receiving line at the church or reception, so I'm trying to figure out the logistics of this. If we walk down the aisle and out, everybody will still be inside the church. If we stop at the door and wait for everybody, then we have an awkward forced receiving line anyway. Is there some proper way to do this, or should we just organize the throw at the end of the reception (which is what I think every single wedding I've ever been at has done).
