I went to a wedding last May and noticed everyone was in the aisle taking pictures and it ruined the professional photos. After that, i decided I was going to have a phone free wedding ceremony. What is the best way to announce this? For sure I am putting a chalkboard sign outside of the entrance but there are a lot of doors so I'm worried some people won't see it. Is it appropriate to use a program insert? What are other good ways to get word across without being rude?
