I heard about this idea the other day when I popped into St Michael's church office and I thought that it sounded rather lovely. At a wedding, instead of the bride having a bouquet that has been made earlier, single flowers are given to people in the congregation, and as she walks up the aisle the bride picks them up until she has a whole bouquet. I like the level of interaction in the idea and the fact that (potentially) everyone has something to give to the ceremony. (Although in practice, unless the congregation were a small one, I imagine that you would have to somehow confine yourself to the people nearest the aisle, unless the congregation could spread out like a guard of honour).
Often what makes the difference between a creative worship idea that works and one which doesn't is thinking through the logistical difficulties in advance and solving the practical problems in order to help the worship run smoothly. Having a person to check ideas with will often flag up these difficulties that you haven't spotted so that you can solve them before everything goes pear-shaped.
