A festoon is "a string or chain of flowers, foliage, ribbon, etc., suspended in a curve between two points." Modern usage has expanded the definition of the verb form to mean "to fill or cover", but dictionaries tend to maintain the narrower scope. Festoon derives from the Italian feston, "decoration for a feast."
