Some people use decorations for their ceremonies or dinners.
Fun things to use for decorating are autumn leaves or flowers, pumpkins, gourds, and autumn fruits and nuts. Candles also make pretty decorations for Samhain. The festival of Samhain has been celebrated for many years and is considered, by many, to be the origin of many Halloween traditions.
