Buckle up and get ready for Finnish fun as Katrilli brings us the St. Urho party, with music by Folk Voice. Katrilli members will teach Fininish dances before the party, so make sure to arrive by 7:30. The evening will feature lots of mixers and dances that newcomers will be able to do. Get in the spirit of the evening by wearing purple and green. Admission for this dance will be free. Class, 7:30 p.m.; dance, 8:30–11 p.m. Info: www.skandia-folkdance.org or (425) 954-5262.
