I've been seeing a lot about cake bags or little cake boxes that you can send your guests home with. I wasn't planning on going with a big cake, and only have invted 100 guests, but thought if I ordered a bigger cake maybe sending them with a slice would double as a wedding favor? Has anyone ever seen this done. Also, who would actually put the cake in the boxes or bags for me? It seems like a tedious job and I don't really want to pay someone to do that unless absolutely necessary. Maybe that's a courtesy service?
