You may not sell or otherwise profit from this code without my permission. I was recently best man. The most nerve-racking element was holding onto the rings for the ceremony. A good tip that I have is to put both the rings into a small match box. You then have a reassuring 'rattle' - so you can put it in your waistcoat or pocket without the worry of the rings disappearing into the lining etc.
Handkerchiefs make great gifts for attendants and parents.
Just before my wedding, my sister gave us handkerchiefs to carry with our bouquets. It came in handy when I wiped my father's tears at the altar. Also, decorate a box of tissue using fabric scraps, lace, notions, etc. I told her that she could choose a style that would most flatter her figure as long as it was in the same colour as the rest. I also jokingly added that she could buy some weights and work out 5 minutes a day to get rid of the flabby arms that were causing her grief if only it bothered her.
