Generally, each household prepares one "badnjak", although more are cut in some regions. Depending on the local custom, Montenegrin Serbs may fell two, three, an arbitrary number greater than two, or the number equal to the male members of household plus one. The latter means that each of the males has a log associated with him, with the thickest log representing the head of household and the thinnest linked to the family's prosperity. If there is only one man in the household, three rather than two logs are prepared. The logs may be cut from different species of tree. In parts of the Bay of Kotor, each household prepares four sets, as they are burned there not only on Christmas Eve, but also on the eves of New Year's Day, Epiphany, and the Feast of Saint Sava.
