Bridal Wreath ice Ring
We have seen suggestions of freezing orange blossoms, lily of the valley, stephanotis or other bridal flower in an ice ring as a decoration. For the wedding reception brunch, we're not sure what it would do to the flavor, but it would be beautiful. You might freeze the flowers in large ring of ice, set it on a tray lined with leaves and set punch bowl in that.
