Cap the jar loosely and place in hot sunshine for 3 - 4 hours to brew. Remove tea bags. Flavor and sweeten to taste with sugar, fruit juice or sweetener. Refrigerate unused portion within 5 hours of brewing. That way when the ice cubes melt they won't water down your tea.
Some people put edible flowers in the ice trays before freezing.
How about using a large stir stick or tooth pick and slide different berries on it. You could use a sprig of Mint or a slice of orange or lemon. Now don't forget to Frost the glasses. You do this by putting the glasses in the freezer before serving the tea. Peppermint or molasses sticks are wonderful with hot cocoa, too.
