Before the festival, people paint homes, shops and classrooms in the traditional Halloween colours, orange and black. Some people make costumes at home. Some people buy them in shops. People also make decorations for the festival. These decorations look like witches, black cats, ghosts, skeletons and jack-o-lanterns. Jack-o- lanterns are pumpkins that are cut to look like faces.
