Thanks Geoff.....I like no. 6!
Unfort an assistant I don't have. My friend, who is the Daughter-in-Law of the Anniversary couple, will be able to help with organising .... getting the families together when their turn is up etc. With the main photo, I am seating the Anniversary Couple in the front then I will add the adults and then the kids. I am lucky because all the children, bar one, is in their mid-late teens, so they will be able to stand around without being too bored!!
