I think I'm getting a little confused. I used to think the receiving line was where you, like, throw rice or birdseed or light sparklers at the couple as they leave. But then I thought it was right after the ceremony when they hug everyone and everyone says "congrats," etc. So which one is it? Also, my reception venue doesn't allow throwing of ANYTHING or sparklers. I was thinking of doing bubbles, but it will be dark and that would be kind of pointless. Does anyone have any creative options we could do instead?
