When saying goodbye to the happy couple after the reception, or the wedding has concluded there is usually something thrown by the guests. Here are a few environment friendly ideas:
wrap ribbon around white small sticks. When the couple comes out everyone releases the ribbon and it looks like a river of streamers.
Throw bird food. We all know rice is bad for birds, so why not throw something that is good for them to eat?
Of course there are the infamous bubbles. Feel free to make your own, but bubbles are pretty cheap.
You can also give each guest a sparkler. When the couple is about to come out, light the first guests sparkler on each side and have each guests light their sparkler from the previous persons. It looks fantastic at night time.
