Children all over Finland dress up like witches or wizards or cats, whatever they want. Beforehand, they prepare willow branches and decorate them with feathers and crepe paper. During the morning on Palm Sunday, they do a sort of Easter trick-or-treating. They visit friends and neighbors, give them a branch, and recite this verse: "Virvoin, varvoin, tuoreeks, terveeks, tulevaks vuodeks, vitsa sulle, palkka mulle." It's to wish you and your household heath and a good year. In return, you reward them with chocolate eggs (or other sweets) or a few coins.
Unfortunately, my boyfriend and I were not home Sunday morning for any visitors, but during the afternoon I was able to see some children visiting one of our neighbors.
