My fiance and I were thinking of doing a unity ceremony where we both light and release a single sky lantern (biodegradable of course) with our wedding vows written on it. The ceremony will be outdoors in an open area (next to a lake). I'm just wondering though if it might look stupid to just release one and if it's too early in the night and the effect won't be good. We'd probably release it around 5:30 pm and sunset is 6:30pm. Also, any suggestions on timing of when during the ceremony to do this or good things to say to accompany it?
