How are the St. Lucia Night festivities observed / practiced?

from online web posting about national traditions of Christmas and Advent (St.Nick dot-org): Sweden Swedish families celebrate Saint Lucia Day on December 13th. The oldest daughter wears a white robe, a red sash, and a crown of lighted candles as she serves coffee and buns to other members of the family. Communities celebrate with Saint Lucia parades. Carols are sung in praise of the Queen of Light, who is said, brought hope at a dark hour. Following Saint Lucia Day, everyone starts Christmas preparations. The house is cleaned and gingerbread is made. Bundles of wheat are tied and placed outside for the birds. Holiday breads and cakes are baked. Candles are plenteous for they represent the desire for the return of light. On December 22nd, the darkest, shortest day of the year, candles are even placed in the church yards. Their Santa is a little dwarf-like person known as Jultomten, who delivers presents on Christmas Eve. Long ago funny little gifts called julklappar, were given by a secret rap on the door. Many families attend a pre-dawn church service celebrating the birth of the Christ child. Special Christmas foods are lutefisk, a dried cod fish that is boiled and eaten with melted butter. Kringle, sandbakkels and crumcake are favorite Christmas sweets. http://www.saintnick.org/html/traditions.html
