Luminata (September)
If you are in Seattle in September, try to take in the Luminata. Join in on an enchanting walk around Green Lake after dark with lanterns and friends (if not now, certainly by walk's end). Most lanterns are homemade of bamboo, reed and tissue paper, but do not rule out various other charming/oddball materials and techniques.
The promenade usually pauses halfway around the Lake at the Seattle Public Theater hill, where everyone enjoys a hot beverage and cookies. Someone rightly said, "Luminata is the event with the greatest sweetness factor."
