Is 1 between 2 people ok? I am making my own and to try and keep costs and time down i have thought i would do one between 2 where possible. If someone is attending on their own then i will account for one alone for them etc and one for my reverend. Also what is best for us should me and OH have one each or will it work with 1 between the 2 of us aswell? What should i do?
