The look of composite roses as bouquets is definitely making a comeback. Usually your florist will take one rose and wire several rose petals around it in order to create an illusion of one big rose.
I think this look is especially awesome for bridesmaids and can easily be recycled for your use for your cocktail hour reception decor. It would be so easy to pop one in a case that is already sitting on the table. Your guests will still get a wow factor since most won’t remember that is what the bridesmaids were holding.
