For the best effect, use a maximum of two colours and make sure each balloon in the group stands at a different height. Think about how you’re going to secure them and make sure they suit your other table decorations - you could even tie them to the backs of chairs. When you’re choosing your balloon expert, ask to see photographs of work they have done and, if at all possible, find out whether you may be allowed to look at a room they have decorated for someone else, whether it’s for a wedding or another celebration. Other room decorations are equally important, see our separate sections on flowers and favours.
